An Experimental Study on the Evaluation of Hydration Heat of Low Heat Concrete (in case of Belite rich Cement)

저발열 콘크리트 수화열 평가의 실험적 연구 (Belite rich 시멘트 중심)

In hardening massive concrete, the heat of hydation gives rise to considerable thermal gradientsand thermal stresses, which might cause early age cracking. This paper deals with the results of evaluation of hydration heat of low hear concrete, using Belite rich cement (low heat cement) and compared with OPC, slag added cement and fly ash addedcement. Result of evaluation of hydration are presented in this paper. The concrete made with Belite rich cement gets low temperature of center point and low thermal gradients between surface and center points.
