It is very important to be conscious of the environment in today’s world. An ever-expanding number of environmental issues are encouraging us and to opt into green solutions in any area where it is possible.
Join our presenter, Icaro Mariani, to gain insight on some green solutions for concrete maturity from Giatec in this exclusive on-demand webinar.
Engineering Solutions Associate, Giatec Scientific
Right now, so if you have any questions along the presentation, you can make the questions using the Q&A button and in the Zoom software. You can also raise hands or input comments there, and I’ll be more than happy to answer any of the questions that you may have along the presentation. If I don’t cover the questions right away at the end of our session I’m also going to address all the points and hopefully demonstrate and answer my questions using examples from our sensors.
So, with no further ado, I’m gonna just double check if I have my correct screen being shared. Just give me one second. OK, there we go. So, in this presentation I am also going to toggle between the PowerPoint presentation and also a live demo on how you can use the maturity and how you can use AI in your intermixed designs on site. OK, so let’s start here. So, my name is Icaro Mariani, I’m a civil engineer with a master’s degree in civil construction engineering in which I studied the effects of core extraction in different types of concrete with using different sizes and also in different concrete elements. So, my background is in concrete technology, and I also have eight years of experience in the construction industry. Seven of those in concrete batch bands. So yeah, my main focus and my main expertise is on is in concrete technology.
So, what is Giatec? Who we are. We are a company that have as a vision to revolutionize the concrete industry not only with NDT devices, we have our NDT division that measures corrosion rate and reverse. For example types parameters for durability, such as electrical resistivity. Rapid chloride predicatability in concrete, but also our main product is this SmartRock® sensors, so our vision is to revolutionize the concrete industry from the concrete dispatched at directly at the concrete batch plant using hours. SmartRock® Plus producers from you know, placing their concrete on site and getting those results from the sensors. Those results could be compressive strength results, or even flexor or tensile strength pursuits for concrete pavements. So that is the goal that we are trying to implement in the construction industry. Our agenda today we’re going to discuss why this concrete maturity and how it’s important, as some of you already know.
Uhm, what is the concrete maturity method? But I’m just gonna briefly touch base on how it works so later on I can discuss artificial intelligence in concrete and how we correlate. So, it’s the maturity method. Also, time saving analysis using the maturity method. So how you can leverage using maturity sensors on sites to save you time and money, for example, stripping farm works in our regular high rise building or even you know, stressing cables on PT decks.
Concrete maturity ecofriendly. I also gonna bring it up some examples of how many cylinders you can reduce by using the maturity method and also how huge is the impact of the cement in the mix is that you are using all sides, so if you know that you have an overperforming mix and you can reduce the cement content from that specific mix, you are drastically reducing CO2 emissions from that and also concrete maturity, cold weather and energy savings.
So, I presented a webinar on cold weather. Uh, my gosh. Cold weather season so I’m gonna briefly touch base on how you can use maturity meters to reduce the amount of heaters that you use on site or the the amount of time that you have those heaters on. Especially now in the northern hemisphere that you are using if you use heaters on site to ensure that your coat has enough strength, especially at the early ages. So why this concrete maturity so?
To begin with, we need to know what is the challenge when we cast our concrete, how do we measure the quality of concrete? So typically, worldwide people measure the quality of our concrete by testing the compressive strength. Uhm, of course there are other methods, but this is the most common way to evaluate if you are the concrete that you are receiving is indeed what you ordered. So, there are basically three ways to measure that future specimens that you cast on site and leave them close to the structure to represent the real current condition that your structure is being subjected to, but this does not represent the actual concrete EC2 behavior because it’s a smaller volume and there’s a different temperature because it exchanges temperature with the environment much. You know much more than the concrete element, which is a higher volume.
Let your specimens, uh, this is for QC purposes. Basically, where you are making sure that the concrete that you were you received is indeed what you expect. But this does not represent a real green conditional site, because you’re creating your concrete in a lab environment at 70-72 degrees Fahrenheit. Or between 20 through 23 Celsius in a cushion chamber or even water tanks. And we also have maturity meters, so the maturity meters. They rely on the maturity method to calculate the compressive or the flexural strength of your concrete. So, they use the maturity method that has been in place for a while now. This is not a new method, but only now we have the technology to use this method on site to calculate the compressive or extra strength on circle.
So, moving forward here, limitations of concrete cylinders, inaccurate temperature conditions, delayed results, limited information, local variations, and low visibility. So, among others, so when you catch your cylinder, how can you be sure? That, for example, here is a pitch deck and casting those cylinders and leaving those cylinders close to the anchor location. How can I be sure that those cylinders are behaving equally as my concrete element does? Then colocation? I can never be sure, so this is just a representation that doesn’t give us much visibility, nor. Precise information of their real current condition in the concrete element. Moving forward here, I like this chart and I also wanna discuss this discharge charge moving on up. Imagine that we have the same mixed design being delivered on site. First of all, I’m going to show three different temperature profiles, the green one, and the first one is your real concrete element, so the real concrete element.
Uh, so you can’t share, for example, a column or a wall. You’re spiking at 100 degrees Fahrenheit, let’s say are around 38 Celsius, and then slowly comes down if your weather condition is around 10 degrees Celsius or 50 Fahrenheit. When we cast a cylinder, a lead cured cylinder, it remains at the job site from one day to another, typically in cure boxes, but the temperature will eventually go down to 50 and then go up to the 70s or 20s on Celsius. That is electric condition and the last one is the future cylinder where the temperature just should, you know, dampened condition and remains the same throughout the time. Just fluctuation between day and night. So how can we expect that those three different temperature profiles are going to achieve the same strength? Especially in the early ages? You can never assume that it’s the same mix design indeed, but they are submitted to different conditions, so this is the main point when we discuss maturity on site.
Uh, just to summarize, what is the method on demand? The maturity method is known discharge destructive method to estimate the real time strength development off in place concrete, especially in early ages, so we’re not using maturity to replace our 28-day cylinder. We’re using it to perform your operations much faster if you need to it perform, works within three days. For example, you wanna know when you reach that target 3000 KSI or 20 MPA. You wanna know that right away so you can proceed with shared operations on site and that you know that time that you’re saving is also money that you’re saving. So that is the concept behind maturity, and it can be applied for several applications. So front farm work, removal to precast. Uhm, mask awkward opening traffic to opening concrete, pavements, traffic, slab colors, beads foundation. So, there is a huge priority of applications for the maturity method.
And tricks being here, the goal of what we’re doing here is to correlate compressive strength versus maturity. So, the sync factor here, the chart that we’re looking is and compressive strength in PC versus Fahrenheit hours. But if you’re in Canada, or you know in another place that use the metric system you can use MPA and Celsius hours as well. The correlation is the same, it’s just, it’s just the unit that is different, but the correlation between maturity and strength would be the same. So, we’re building this relationship to further on use this relationship to your concrete element. And its uses basically in North America what we normally see is the Nurse-Saul equation or the temperature time factor in which we are catching this area.
So, sorry I will have further down like a chart as amplifying what we’re doing so this is what we’re doing we have the temperature profile of your concrete. We have the daytime temperature, which is the baseline of the calculation, typically at 30 Fahrenheit or zero degrees Celsius. ASTMC 1074 recommends these data on temperature. If you’re using a cement type one, but if you’re using different types of cement, the data and temperature can also be calculated, so this is the baseline of calculation, and typically as 32 or 0 Celsius is a conservative number, then we’re calculating the area under the curve, so this is what we do with the maturity method. We calculate the area under the curve throughout a certain period of time and correlate this area with break results. And then we’re going to keep calculating the area under the curve for different breaks at different ages and creating and building their relationship. So, it’s basically the summation of this area?
And, uh, how does it work if, uh, if eventually our temperature drops below the daytime temperature? What happens? So, this is a question that I get a lot. Let’s imagine you have cast your concrete. It’s cold and the temperature in one day drop let’s say yeah 24 Fahrenheit or minus 8 Celsius. What happens? So, this is an example of what happens. We are calculating the area under the curve and the temperature here is around 70, 70, so we are hoping we’re accumulating this, but once it drops below the freezing point or the data temperature we’re not developing strength, so between the, our five and six in this example, our concrete didn’t gain any strength.
So instead of gaining time with the sensors, you’re actually being more. You’re bringing safety to your operations because you’re really catching what is going on with your concrete instead of relying on cylinders that are needed perfect condition in a moist room at 72 for having. I have an example here and, uh, this is a real case example that happened here in Ottawa. Uhm, nothing detrimental to the structure itself, but this is an example of what happens when your temperature drops below the data, so this is the temperature profile of the concrete element. This was the lab on deck, so we see this spikes of the iteration. The iteration spike right here.
So, this was during winter, so there is the thermal exchange with the environment so that temperature eventually will drop and for a certain period of time between the five and a six we were you know, for more than 24 hours below the daytime temperature, so what happens in this period? We have this strength development offered concrete based on the maturity calibration that we did input to the system, so we’ll see that the strength development, it flattens at that specific time here, so this is the beauty of the system. You can track down this slow gain and then we when it comes back up, especially if you’re you know, in cold weather and you’re worried, worried if your concrete is no, it’s gonna withhold at least one freezing and falling cycle. You can be sure that you have those 20 MPA or 3000 PSI minimum requirement according to ACI so you can have peace of mind that your concrete is withholding the stresses of a freezing to win and cycle for example. So yeah, I forgot you mentioned 20 hours here, so more than a day.
No, we’re going to jump into the core of the presentation and the main goal of using maturity as a green solution to job sites. So, what is artificial intelligence in concrete. We have Roxi so you have Google Home. You have Alexa in your home to just say for example hey Google, turn on the lights. With Roxy, we have this in any place to evaluate your own concrete. So, as you have other artificially intelligent systems to help you in your everyday tasks you can have Roxi to help you know when the concrete is really touching your complete sensors on site when can you reduce cement on your mix design or even share maturity? Calibration makes sense with the mixed proportions that you add to the system, so this is the first and unique AI program in the world to evaluate concrete mix performance. So, we suggest free time based on temperature history. It also has a mix validation process that uncovers human error based on maturity calibrations.
It also detects those errors. Suggest improvements based on maturity points and as I said, it’s the first and unique AI system. Uh, I would like to highlight here that if you have, if you want to know more about Roxi after this webinar today, you can reach me out. I’ll be more than happy to send you further information about Roxi. So how does the artificial intelligence in concrete to detect pouring time works? So, this is a typical example. Imagine that you have a huge foundation block and let’s imagine these 500 cubic yards. Or you know 650 cubic meters more or less. So, you’re installing sensors everywhere, at least in five or six different locations to track the temperature, the Min and Max temperature, and also the strength.
And you want to know when the concrete really reached those probes in a 650 cubed commuter poor or 500 cubic yard poor, you’re gonna have let’s imagine around 10 know about about 50 trucks, for example. So, you don’t know precisely when this really concreting those probes. So Roxi here, we identify that your temperature only suddenly changed at this moment. It’s gonna tell you, hey this is the correct pouring time and further on this is going to bring you more precision to the compressive or the strength results that you’re looking into the system because you know when your strength development really started Instead of putting that on a random time that you’re not quite sure.
Mix validation, so this is a result of years of data collection and analysis, so we have the console with place so we have concrete producers not only in North America but throughout the world we have in Europe we have in in Australia we have in other locations as well so uh, with these database share we are able to, uh, kind of study the mix designs with different types of cement and work on that so we can put the mix, the mix proportions in our system and calculate if the maturity calibration is indeed makes sense and further on analyze if we can reduce cement.
And I’m gonna briefly show you how to do it. So, I would just like to mention as well that this is a huge effort for our R&D team that is still working on Roxi. It’s a she. So, on her development and we are getting positive feedbacks from users using this this feature. And the cement reduction. So, I’m going to show how Roxi will calculate the cement reduction and how and I’m going to simplify through, you know real numbers from the project. How much CO2 emissions you could reduce by using Roxi in your project. So, this AI will show how performing the mixes it will also analyze how much pounds per cubic yard could be reduced or kilograms per cubic metre? And as I said, this has a direct relationship with CO2 emissions. Without no further do, let’s go to the Roxi here. So, I’m gonna go ahead and create a mix into our system. So mixed example this is our system. The Giatec 360 dashboard in which you can start creating mixed signs to use into the sensors and we’re going to select the calibration method.
So, as I said, we’re using temperature time factor or the Nurse-Saul equation. Just a heads up if you’re using, if you are in Europe and you’re used to equivalent age, this is also available. You can use the radius equation according to the equivalent age. I’m going to set the date and temperatures so our baseline of calculation at 32 and then, according to ASTM C1074 we have rigs and we have two reference cylinders and those two cylinders we need install two sensors to measure the temperature history and they’re going to correlate this temperature history with brake results. So, I’m gonna go ahead and, uh, select the two cylinders so I’m gonna go to my maturity calibration sensor maturity one that I know that I did install in one cylinder and then I’m gonna go and select the second one. So, this is the typical temperature profile for concrete cylinder in a maturity calibration we see the spike of hydration and then it comes back to around 70s or 20s and Celsius. So, this is like a regular train condition. Then we simply meet. You come here and start in start to add our points.
So, let’s imagine that in this calibration I’m going to add five data points at 1237 and 14. At day one so I’m gonna put in imperial, but if you’re using metric, this is available as well. Just single click. We can go back to metric and put in NPS. OK, so let’s imagine that within two days we already standing at 3300 PSI and I would say that for three days which is our critical point. So, three days and 2023 hours here 4000 I just have two points more, so for seven days, we go to seven days and for seven I have 5800. And my last point, within 14 days we are standing at 7200 PSI. So Roxi already did match the both break times for me to make sure that the temperature profiles are overlaying perfectly and I have our points over here, so Roxi is initially calculating the average maturity from those two cylinders and correlating those with break results and, so I’m going to click next and what Roxi is showing here, it let Roxi check your mix by adding its proportions.
So, let’s go ahead and add mixed proportions. Let’s imagine that did for this mix I was using 540 pounds of cement type one I was also using 300 pounds of water. Be mindful that you share using gallons. We need to convert that to pounds. If you’re using liters, you’re fine. You’re just gonna use liters for meter. And then let’s imagine for fine aggregate 1685 and coarse aggregate 2000 and we also can include other extra ingredients here. Let’s imagine that we’re using fly ash at 160, and let’s imagine that we are using a high range water reducer for answers oz per cubic yard. Heads up here. Depending on the country that you are located, you’re gonna add uh, the additives in a percent, based on the cement consumption or in by 100 weight if you’re using by 100 weight, be mindful that we need to multiply that by the amount of cement that you have to get the real number. In this case I’m just adding 4 ounces per cubic yard, but this could be you know, one ounce per hundred weight.
Then we’re gonna add our specified performance. Let’s imagine that for this mix I expected to reach 3000 PSI in three days. So, I can remove formworks safety margin of 10%. Then for 28 days, I specified performance is 5000 PSI 10% of five inches and an air content of 6%. Let’s imagine this is a winter mix. OK, I’m going to click save and Roxi is gonna analyze our means and she’s going to propose changes if there are changes should be made. So here Roxi is telling me that I can reduce my cement content by 2% if I maintain the same water content. So basically what Roxi is doing here? Is telling us that we can’t reduce cement even though we increase the water to cementitious material a little bit further so because we didn’t put the specified performance through the system, Roxi is evaluating all the brick results that we get input into the system, it is detecting did that our mix is overperforming. So, it is proposing this reducing cement content and if you were able to reduce 2% of cement in your mix you’re making huge savings and terms of CO2 emissions.
I’m gonna go ahead in our representation, to demonstrate how much you could save from it and how you can you know, make your company even more eco-friendly. So, I’m going to start with the time saving analysis. It is normal to expect higher strength results from the maturity method if you compare those with lead two cylinders. As I said before, your corporate element is hydration. Hydration process is much stronger because you have a mass volume there, so therefore you’re developing much more strength. In this case here for example, uhm, our goal was to achieve 3500 PSI if we were expecting our lab cylinders to break at 3500, that will take 24 hours. If we were using cylinders on site half a day, so 13 hours would be achieving our limit because of this hydration spike.
Include ambient conditions less different would be expected. Or the poles could be observed. Imagine that it is minus 15 Celsius. Or, let’s imagine that it’s you know, 10 Fahrenheit outside your concrete is subjected to this temperature, while your concrete cylinders in the lab are not, so you’re relying on those cylinders to stress cables in a pitch deck. So there’s another point to bring it up so the sensors would give you not only our sensors, but maturity sensors would give you this type of visibility.
Back to that chart that I had mentioned before, if we translate those three different temperature profiles in two strength results and maturity, we’re seeing different maturity gains and therefore different strength results. So for the same mix so this is the same mix at these three different green conditions in 24 hours our concrete element, our in place strength is almost at 3000, in 72 you’re standing at 4000, while the other field-cured cylinders are much lower than that. So, this is what Roxi was doing for us when we are doing the maturity calibration steps. It was suggesting that we could save cement from this mix because this specific mix was overperforming, so cement saving as CO2 reduction, how?
Cement saving so these over performance of your EC2 mix allows you to perform the operations faster, but if you’re not 100% interested in you know we speed up the process, but you would like to, for example, improve your mix design and still perform the operations at the same rate that you are used to, means that you can reduce cement in your mix, so less need of cement in the mix. Concrete batch plants statistics basically rely on cylinder bricks turn out wrong so this is that the method of conformity, but the real concrete element could be behaving much higher than concrete cylinders so it’s not the actual concrete element, so this interface with your concrete producer to analyze our mixed performance on site can put you, ring the bell on in terms of how you can improve the mix, but how much? You could improve a mix, let’s imagine that, uh, you are reducing those 2% that we saw before, or even another example that I’m going to show.
If we reduce 4% of cement in the mix, we are directly reducing future emissions. Why? Because on average every ton of cement produced produces .83 tons of CO2. It doesn’t matter if we’re talking in metric tons or imperial tons. It is their relation is the same. So, this .83 is for the North American market. Depending on the region that you are in the planet, it could be different. So, I also mentioned here that if imported, if you’re based in North America and you know that your producer is importing cement for another countries, this rate could be even higher. Could reach 1.2 dependent on the efficiency of the cement factory, so let’s do an example here.
We have a concrete strength is 6000 PSI and the target strength is 3000 PSI around 20 MPA. OK, this is the mixed proportions. We have 600 pounds of cement, 250 pounds of water and the water to cement ratio is .416. OK, by using the sensors I already said that our target is 3000 PSI in three days. Our sensors are telling us that we are at 3500 PSI so there’s a gap of 500 PSI hear that we could reduce from the mix if we pass this mix into Roxi and Roxi tells us, hey, you can reduce for cement 4% of cement even if you increase your water to cement ratio ’cause obviously you don’t want to lose workability if you simply reduce cement, maintain it the same water to cement ratio you are, you know, reducing moisture from your mix and you eventually need additives to give the flow that you want or the workability that you want. So, in this case we’re keeping the same the same slump with the same amount of additives.
So now we reduce our cement content to 576. So, this is giving us 24 pounds less cement in every cubic yard. OK, so our three-day sensors are still showing 3200 PSI. This gives us a safety margin, right? So, if we calculate this difference, it’s 24 pounds of cement less in a 500 cubic yard pour that that is giving us 6 tons less CO2, less sorry, less cement in the mixes, right. If we multiply that point by .83, we’re saving 5 tons of CO2 just in one pour. So, imagine what you could bring to your company when you say that you’re for every port that you cast you’re saving 5 tons of CO2 emissions. More than that, imagine a huge project. This is a high-rise building, for example, 15 floors, two pours per story. You know 500 cubic yards, so we are saving 150 tons of CO2. So, this is the number that you can associate to you when you were, you know, designing. When you’re in the project side of things, so you can anticipate this, so if you can see how much you can save beforehand, that can, you know have a huge impact in the environment more than that.
Maturity oh sorry, maturity is also eco-friendly in the terms of your reducing emissions during transportation and also cylinders. This is a typical flow. I should have an animation here. I forgot to add animation, but this is a typical flow of the construction and the concrete producer. The concrete is batched at the concrete batch plant. Then we transport this concrete to the job site. You pour your concrete. Then you get field or lab cylinders. Then the next day you’re going to pick that up moved into the lab, and then after the lab calls you, hey, you’re good to go. Go ahead and stretch your cables, sweep your forms. So sometimes this process can take a while, right? But if we reduce this process here.
Just keep in mind we’re not eliminating your 28-day cylinder, we’re eliminating your early age brake cylinders. Instead of doing that process, you’re installing sensors. You can reduce or even eliminate feud cylinders, and you also reduce transportation to the lab, right? Because if you’re using feud cylinders, the level needs to come to the job site you pick the cylinder in three days and if you don’t have enough strength, you need to come back at 3 1/2 days or four days and pick another to break that cylinder to make sure that the feud cylinder has enough strength. So, your reduces your two emissions with this transportation side of things. Amount of cylinders as well. So, in an average so you have less concrete waste at the job site and at the lab.
So, when an average of three to five cylinders, every cubic yard, every 100 cubic years, or 80 cubic meters, this is an average of the North American market. Of course, this depends on the region that you are the country that you are. But this is like an average that we see typically with the maturity only 28 days, cylinders would be needed. OK, so if we translate those numbers we could save up to 225 cylinders, so this is a waste management. So, if you can also on top of this huge emissions that you’re saving, if you can also mention that you are reducing 2000 sorry 22125 cylinders, you can also bring this greenimage to your project.
Lastly, here I gotta discuss about cold weather and energy savings. OK, let’s imagine that you are in cold weather and you are placing your concrete and you’re turning on heaters to make sure that you have enough strength on your concrete to perform your critical operations. So concrete pours and at 10:00 AM on Day 0 then your target strength is 3000 PSI 20 NPA to strip forms and turn off heaters. OK so this is basically the layout that I I wanted to discuss. If you have sensors in your element, you’re reaching your target 3000 PSI or 20 MPA within 4:00 PM the next day after pour.
If you’re waiting for the lab or you know to pick those few cylinders that are left at the job site to pick them, then that specified each you aren’t waiting to 72 hours so we have a 42 hours gap here. So, this is a real case example. Of course this can vary according to, you know depending on the job site and if we take those 42 hours and translate that to the cost and also the amount of CO2 remissions that you’re using without a gas heater or even electric heater. This can be huge. In terms of money, you can save as well, but on the environment side of things, it can be even greater. In this case we are saving in per story $145 per story only with the heaters because we have six heaters. With this average costs per hour, so point $0.20 kWh and total heating costs. We would come to 3.46 so we’re saving those 42 hours. I can send this this table to you later if you want, but this would be the average savings that you would have with the cylinders. Or if the sensor is actually on site. Also, in cold weather, no matter if you are using propane or electric heater so the system will allow you to know when you are reaching your target.
This will trigger an alert to you and other team members, letting you know. Hey, go ahead, remove your forms, or continue with your job site operations. You don’t need to wait anymore, you can go ahead. So, this type of solution is available and also with our system or another system that uses a constant connection to the sensors you can have live information, so with our SmartHub system, you could receive the alerts right away. Of course, sometimes you’re gonna receive the alerts at 3:00 AM letting you know hey, you have enough strength to proceed with operations, but at least you can go to the job site the next day with peace of mind that you won’t have any delays at your job site. I also like to mention for PT application this is super helpful because stressing cables is a very sensitive operation, so relying on sensors to know the actual strength of your concrete, you can prevent incidents so cables it can be a hazard if you do not have a minimum strength from the durability perspective.
Uh, if you don’t have any cracks close to the region of your anchor location so in the middle of lab you have a high bending moment. Closer than collocation have a high concentration of stresses because you are pulling the tendons from that place. The last place that you pulled, you conquered. The last place that you’re starting to strength development so all those locations you can store sensors to be more accurate in terms of safety because you know what. What is your worst-case scenario or what is your critical location and also waste reduction? So, if you don’t need to repair anything with your tendons or any cracks you know, shield cracks or plastic cracks, for example, you don’t need to waste materials with repairs. And lastly here I thought that was the last so uh, from the durability side of thing we like should mention about mass concrete. Depending on the country and the location that you are or even the project and the specs that you are using sometimes you’re sticking with a maximum temperature differential of 35 Fahrenheit or 20 Celsius between core and surface.
Uh, I’m not gonna, you know, go in depth of the concepts behind this limit. But uh, our focus here is to develop new mindsets. So, if you’re using the maturity correlated with, for example, mass concrete application, you couldn’t know that your concrete has enough strength to withhold stresses due to thermal control due to terrible exchange. If your core is expanding and your surface is contracting, you’re generating stresses, but you’ve, if you have a sensor in your element telling you that you have 30 MPA or let’s say 5000 PSI you also can have peace of mind that your concrete won’t crack, and your concrete is not. You know that those stresses are not being detrimental to the durability of your concrete.
And, uh, yeah, I did right here that the dashboard allows and enables you to have control over your data. So, the dashboard that I was showing before in which we created a mix. You can also build those temperature differential analysis cases to better understand how your concrete is performing outside. One last thing here, uh. Today we did discuss about the green side of things and how maturity can help you to be more eco-friendly on your projects.
But tomorrow we also have the net zero conference, so the net Zero construction conference. So if you go to our LinkedIn page, uh, Giatec Scientific. Search it there. There is a a link to subscribe for this conference. It’ll be a super interesting conference. We have Major GCSsin North America participating. We have also well, we’re R&D manager Andrew. He is going to present in this conference. But we have a market leader discussing how we can, you know, tend to be more green in the construction field, so this net zero construction conference is a must go in my opinion, if you’re interested about how to turn your projects even more green. So, with that I would like to end my presentation. I know that there’s a lot covered in terms of how maturity can help your projects to be more green, but hopefully this was useful to you know open minds to this new concept. And if you have any questions this is my direct contact is email@example.com you can find me on my LinkedIn as well.
