EFFECT OF MATERIALS COMPONENT ON HYDRATION HEAT OF CONCRETE

摘要

The effect of mineral admixtures and chemical admixture on hydration heat of concrete wasstudied. Results shown that, the addition of SL (blast thrnace slag) could bring forward theappearance of the largest temperature peak of hydration, while the addition of fly ash couldretard it. Condensation regulating agent (NS) could increase the largest peak value of hydrationtemperature and bring forward the appearance of the largest temperature peak of hydration.
