Potholes—An Expensive and Recurring Problem for Cities
Potholes are a huge problem all over North America, but nowhere are the detrimental effects more evident than in Canada’s capital, Ottawa. According to CTV News, the city experienced over 40 freeze-thaw cycles during the 2018-2019 winter, which created tens of thousands of potholes that need to be…
Testing Concrete Quality and Durability in Seconds with Surf™
As the demand for new concrete structures continues to increase, contractors need better and more efficient ways to test concrete quality and durability. For this purpose, several techniques have been developed and studied. One of those is Rapid Chloride Permeability Test (RCPT), which measures the concrete’s ability to…
Q&A: Norman Lauzon Explains how Concrete Maturity Sensors are Changing the Jobsite
Norman Lauzon is the Senior Project Manager at Ledcor, a successful and diversified construction company that partners with projects across North America. Norman has more than seventeen years of experience in the construction industry and has managed the development of hospitals, airports, light rail transit, and a variety…
Concrete temperature plays a critical role in the success of any construction project. As one of the most commonly used materials in the world, concrete must be handled with precision, particularly when it comes to temperature control. If not properly managed, temperature fluctuations during the curing process can…
The Importance of Concrete Temperature Gradients
Minimizing the risk of cracking is critical for maintaining structural integrity and increasing the service life of a concrete structure. This is an important consideration in all construction projects. Furthermore, it is especially critical in those that require the use of mass concrete, such as bridges, buildings, structural…
Field-Cured vs. Standard-Cured Cylinders: How They Affect Concrete Performance
How do Curing Methods Affect Concrete Field Performance? ASTM C31 is the standard that defines two different concrete curing conditions, standard curing and field curing. This standard dictates the procedures for making and curing test cylinders. At the same time, it can become a problem when an engineer…
Damaged and deteriorating bridges are a major concern when it comes to transportation infrastructures. According to the ARTBA Bridge Report, “1 in 3 U.S. bridges need repair or replacement” and there are over 46,100 that are considered to be structurally deficient. Each year millions of dollars are spent…
5 AI Solutions Disrupting the Construction Industry in 2020
Artificial intelligence (AI) is widely used to solve problems in industries like finance and healthcare, however, the construction industry has generally had a slower rate for adopting such new technologies. This prompted Giatec to launch Roxi™, the world’s first AI program for concrete testing. While Roxi can revolutionize the concrete…
Common Challenges When Measuring Concrete Temperature Differential on the Construction Site
Controlling the temperature of concrete on construction sites poses many challenges. It is critical to keep track of your concrete temperature differential to ensure the optimal quality of concrete. It is also important because improper temperature measurement can lead to failed structures, increased project prices, and longer completion…
Relationship Between Concrete Curing, Concrete Temperature, and Concrete Strength
Although concrete curing, concrete temperature, and concrete strength are three different things with three different meanings, they are not independent of one another. There is a close-knit relationship between these aspects of concrete curing and each facet plays a significant role in the overall strength and integrity of…
What Is the Concrete Maturity Method ASTM C1074?: Frequently Asked Questions
The concrete maturity method ASTM C1074 is a non-destructive approach that allows the estimation of the strength of in-place concrete. The method uses the temperature history of the concrete during the curing phases to estimate strength development. Big Projects Deserve Better Protection Keep mega pours safe from cold-weather…
Maturity vs. Pull-Out: Which Concrete Testing Method Should You Choose?
When it comes to testing compressive concrete strength, there are several methods to choose from. Field-cured cylinder testing is the most common method utilized for monitoring concrete strength on construction sites. For the most part, it has remained unchanged since its introduction in the early 19th century. However,…
Using Maturity to Increase Allowable Concrete Temperature Gradients
With the evolution of the construction industry, we are building structures bigger than ever before. These massive structures are mostly made of concrete and often represent a challenge for many reasons. One of the main problems encountered is the concrete temperature difference between the core and the surface…
Practical Installation Locations of Wireless Concrete Maturity Sensors
The traditional way to determine whether a concrete element is strong enough for critical construction operation is to monitor concrete strength using field cured cylinders. Once the specimens have reached the desired strength, usually 75% of the mix design strength, the project can then move forward and it…
