Properties for Crack Controlling and Watertightness of Concrete added with Crack Reducing Agent for High Strength Concrete

고강도 콘크리트용 균열저감제가 첨가된 콘크리트의 수밀성 및 균열제어 특성

This study is related to comprehending performance for watertightness and crack control of concrete added with crack reducing agent concerning to high strength concrete mixs. It was confirmed that watertightness of concrete added with agent could be improved by evaluation absorption ratio, permeability ratio and pore size distribution of hardened concrete. As well resistance to crack resulted from shrinkage was transferred to better state by the addition of agent.
