Mass Concrete Temperature Differentials: The Importance of Monitoring
https://www.constructioncost.co/mass-concrete-temperature.html
It is critical to closely monitor concrete temperatures regardless of the application or size of concrete structures to ensure proper strength development. Temperature differentials must also be considered when mass concrete structures have a relatively hot interior and a cool surface temperature. Overly high temperature differentials will cause the surface of mass concrete to crack, which will affect its durability and lifespan. There are no specific measurements that define mass concrete. In order to minimize cracking, large volumes of concrete are required to be able to cope with heat generation from hydration of cement and volume change associated with it. A dam, a bridge pier and column, a mat slab, or foundations are examples of mass concrete.
