Controlling Temperatures in Mass Concrete

Understanding mass concrete is the key to controlling temperatures and ultimately saving time, effort and money.
Specifications generally limit temperatures in mass concrete to prevent cracking and durability problems. Temperature limits are specified to seemingly arbitrary values of 135 F (57 C) for the maximum allowable concrete temperature and 35 F (19 C) for the maximum allowable temperature difference between the center and surface of the mass concrete section. Typically, the contractor must meet all of the specification requirements, but without a good understanding of mass concrete, keeping concrete temperatures within limits can be a difficult task.
