Abstract:Recently in Japan, super low-heat cement (SLHC) with a much lower heat of hydration than the moderate heat portland cement generally used in massive concrete structures has been demanded for reducing the thermal cracking of mass concrete. To satisfy the requirement, the SLHC (heat of hydration: 167 kJ/kg at 28 days; compressive strength: 30 MPa at 28 days, complying with Japanese industrial standards), incorporating Blaine fineness > 600 m¦/kg and a large amount of ground granulated blast furnace slag (GGBS), has been developed. The effects of fineness and content of GGBS on heat of hydration and compressive strength of cement are described. Included also are test results of the bleeding ratio, compressive strength, adiabatic temperature rise, drying shrinkage, and carbonation depth of concrete using the SLHC.
