Abstract:
Portland cement was mixed with slags at different fineness and replacement levels and hydrated at 10, 20, 35, 50, and 65 C. The temperature rise of concrete containing slag was reduced when the slag replacement level was 70 percent. The hydration of slag was accelerated at temperatures between 20 and 35 C. The amount of heat liberated by the mixtures was greater than that of the reference portland cement at temperatures 35 C or higher. It is therefore evident that in mass concrete containing slag, the adiabatic temperature rise need not be lower than that of the concrete containing only portland cement.
