Initial Behavior and Shrinkage Properties of High Strength Designed Concrete added with Special Inorganic Additive(SWP-2H)

특수 무기성 혼화제(SWP-2H)가 첨가된 고강도 설계배합 콘크리트의 초기거동 및 수축특성

This study is concerned with application of SWP-2H with performance which could be improved compressive strength, crack control of high strength concrete ranged from 35MPa to 70MPa. Expermental data showed that initial. behavior of SWP-2H added concrete had a similar tendency that of non-added concrete. As well crack resulted from autogeneous and drying shrinkage and compressive strength were well controled or elevated by application of SWP-2H.
