Long- Range Remote Monitoring Capabilities

When paired with SmartHub Long Range, contractors can have an extended monitoring range up to 1000ft, giving them a full control on concrete temperature data from any devices for their largest job sites.

According to the American Concrete Institute (ACI), mass concrete is any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from the hydration of the cement and attendant volume change to minimize cracking.

Temperature monitoring in mass concrete structures is a critical practice for ensuring the integrity, strength, and longevity of concrete. Due to the exothermic nature of the cement hydration process, large volumes of concrete can experience significant temperature gradients between the core and the surface. These gradients can lead to thermal stresses, which may cause cracking and compromise the structural integrity.

Monitor Temperature Differentials

Monitoring temperature gradients in mass concrete elements becomes a vital task to ensure the difference in temperature between the core and the surface or edge does not exceed critical thresholds to prevent thermal cracking.

When pouring a mass element, construction professionals can place multiple sensors at different depths (using different cable lengths) if required. The dual capability simplifies its application in mass elements because it performs surface and core measurement simultaneously with one sensor.

Optimize Curing Conditions

According to ACI 207 specifications for structural concrete, the maximum concrete temperature differential should not exceed 35°F (20°C) during curing. In mass concrete projects, like piers and large foundations, heat generation outpaces heat dissipation during curing, causing overall temperature to rise. Due to concrete’s slow heat release and low thermal conductivity, temperature gradients can form, trapping heat within the concrete.

This slow heat release can result in early-age thermal cracking. With SmartRock sensors and threshold alerts, one can take proactive measure and protect the element to ensure compliance with the specs and meet service life requirements.

Thermal Modeling

Our thermal model feature allows users with mass concrete elements to experiment with different inputs and produce forecast scenarios. Users can outline the anticipated behavior of the concrete at various depths to make sure they are prepared for anything. This user-friendly feature can be leveraged by multiple stakeholders to optimize planning, save time, validate important decisions and more. Thermal modeling allows users to optimize their mass concrete plans, validate cooling for temperature requirements, build thermal control plans and alter mix design iterations without physical testing. It is all compliant with ACI 207.2R. Read more about our thermal modeling feature here.

Ensure Compliance with Specifications

Many engineering projects have strict specifications regarding the maximum allowable temperature and temperature differential in concrete to prevent cracking. Real-time monitoring with SmartRock Long Range sensors helps in documenting compliance with these critical specifications.

New Generation Technology Part 2: The SmartRock® Long Range and its Applications

Every concrete professional aims to perform critical operations faster and with the highest possible quality. Remote monitoring systems such as the SmartHub™ Long Range developed by Giatec are valuable tools for this need. Following the first part of the long-range series, this blog will delve into the applications of the SmartRock® Long Range. Fully Embedded Wireless SystemsThe proliferation of wireless sensory technology has been incredibly helpful in harnessing vital information from structural elements in the last couple of decades. A lot of construction projects are taking advantage of this technology and have fully embraced embedded solutions. This is because they are reliable and easy to use, giving real-time data of the in-place element. Due to this added value, some project specifications will specifically require the use of fully embedded and wireless systems. However, despite technological advances, there are certain jobsite characteristics where the range of data transmissibility with standard solutions could be a challenge. Also, there could be a demand for real-time monitoring of concrete conditions, which requires constant data acquisition from the sensors installed. Remote project locations and on-site structural elements with limited accessibility of human personnel could hinder the frequent acquisition of data. In turn, this presents some limitations…

The Importance of Monitoring Temperature Differentials in Mass Concrete

The Importance of Monitoring Temperature Differentials in Mass Concrete

Closely monitoring concrete temperatures is critical for ensuring proper strength development of concrete structures and concrete sustainability regardless of their application or size. However, when it comes to mass concrete structures, temperature differentials also need to be considered due to the risk of a large difference between the relatively hot internal temperature and cool surface temperature. If a too-large temperature differential occurs, the surface of mass concrete will start cracking, which is detrimental to its durability and the length of its service life.What is Mass Concrete?Mass concrete isn’t defined by any specific measurements. According to the American Concrete Institute (ACI), mass concrete is “any volume of concrete with dimensions large enough to require that measures be taken to cope with generation of heat from hydration of the cement and attendant volume change to minimize cracking.” Some examples of mass concrete include dams, large bridge piers and columns, mat slabs and foundations.Read how Concor Construction handled temperature monitoring in their mass pour here!It’s important to note that smaller structures may also be categorized as mass concrete depending on several factors, such as type and quantity of cement, volume to surface ratio of the concrete, weather conditions, concrete placing temperatures, degree of…
