Reducing effect for Hydration Heat of High-Strength Concrete according to Admixture Types and Replacement Ratios

혼화재 종류 및 대체율에 따른 고강도콘크리트의 수화열 저감 효과

The hydration of cement paste occurs when the cement is mixed with water. During the hydration, hydration heat causes the thermal stress depending on the size of concrete and the cement content. Especially in the high-strength concrete, we must give care to the concrete due to its large cement content. In this study, conduction calorimeter and concrete insulation hydration heat meter were used to investigate the hydration heat characteristics of cement and concrete. To reduce hydration heat of high-strength concrete, several types of replacement of fly-ash and blast-furnace slag powder were used in this experiment.
