Thermal cracking can affect the structural integrity of concrete and can be a very expensive problem to resolve when it occurs. For mass concrete work, proper planning involving expert help in the design of mixes as well as careful monitoring temperatures after placements is the best way to avoid problems. … See more There is an increased focus on mass concrete now because of the demands placed on it. Concrete elements are getting larger, there are often requirements for increased flow-ability during placement, … See more Contrary to what you might think, thermal cracking can happen to work much less than four feet in thickness. An example would be an exterior eight inch thick slab-on-grade. Some of the conditions that can cause thermal … See more When mass concrete is being placed, electronic temperature sensors are cast into the anticipated hottest and coolest locations of the placement. The more sophisticated … See more WebJul 10, 2024 · The risk of early-age concrete cracking depends on the capacity of hardening concrete to support the thermal stresses caused by the exothermic nature of the hydration process. This has been ...
