As reinforced concrete structres have become large, cracking coused by thermal stress is becoing serious problem. For reducing heat of hydration, that is approximatel 55 cal/g at ate of 28 days, which is about 35 and 20 cal/g lower than that of normal portland cement and moderate heat portland cement, respectively. The strength of the concrete using this cement was found to be about the same as that using normal portland cement. Nevertheless the adiabatic temperature rise of the Super Low Heat Cement concrete was approximately 10℃ lower than that of normal portland cement. The same tendency was recognized when used for concrete with segregation resistivity in water, too. Therefore, it is evident that use of this cement is very effective for reducing the temperature rise of mass concrete members, in the atomosphere or in water.
