Predicting Fresh Concrete Temperatures Concrete ...

Mar 01, 2005  The American Concrete Institute (ACI) has developed formulas in ACI Committee Reports 305 and 306 to predict the temperature of fresh concrete. These formulas use the proportions and the related specific heat of each material to determine the overall concrete temperature. Specific heat of both aggregates and cementitious materials is about 0.22.
