An experimental study on low-heat type blended cement containing ground granulated blast furnace slag is reported in the paper. The influences of factors such as mixing ratio and specific surface of blast furnace slag and the mixing ratio of gypsum (S0_3) on heat evolution and strength development characteristics of cement and concrete were ascertained, and a cement of a composition providing favorable strength development while generating lower heat was proposed. Thus, a blast furnace slag cement of low-heat type has been attained. This blended cement is suitable as a cement for controling thermal cracking of mass'concrete structures requiring comparatively high strength.
