Abstract:
Temperature rise was evaluated for two comparable batches of concrete produced with typical proportions of aggregates. While the cementitious material in one batch consisted of portland cement and Class F fly ash, the cementitious material in the second batch consisted entirely of a liquid-activated Class C fly ash system meeting the performance requirements of ASTM C1157/C1157M-11, "Standard Performance Specification for Hydraulic Cement." The more conventional binder system resulted in a much greater temperature rise than the liquid-activated Class C fly ash system. Thick concrete elements were modeled to determine how the binder systems would affect construction of common structural elements.
