In the present study, the fundamental property related to thermal crack resistances of a high-strength concrete (BBFA) using blast furnace cement type B mixed with fly ash and heat control type expansive additive was experimentally examined. And the following results were obtained. The adiabatic temperature rise (K) of BBFA is same as or smaller than that of a low heat Portland cement concrete, and there is a possibility of remarkable restraint effects of adiabatic ascents. It is expected that excellent thermal crack resistances were obtained from restraint effects of heating values and autogenous shrinkages by heat control type expansive additive.
