Heat Flow Analysis of Mass Concrete

CA has conducted heat flow analyses of mass concrete structures. These have included evaluating the effect of the concrete placement sequence, structural specifications, ambient conditions, and concrete materials and their mix proportions on the cumulative heat generation and internal temperature of the mass concrete construction and thus, on the quality of the in-place concrete. The heat flow analysis and the predicted temperature profiles were later confirmed by field measurements during actual construction. The information developed by CA was instrumental in determining the concrete curing, early age protection, and form removal practices followed by the contractor in the job. CA has also investigated the cause(s) of cracking as a result of thermal induced stresses in other facilities such as mass concrete foundations and precast/prestressed concrete highway structures.
