Mixing Characters for enhancing of durability of the concrete by utilizing 3 component gel contained binder and shrinkage reducing agent

콘크리트 내구성 증진을 위한 3성분계 결합재 및 수축저감제의 배합특성

In this study, as to enhance the efficiency and workability, binder contained 3 types of gels have been used to replacement the OPC. Fundamental properties and length change of the concrete have been tested to evaluate the effect of different binders. The following results could be made as the conclusion. When the binder contained 3 types of gels used, the flowability increased, whereas the air content decreased. There showed some different air content when the component of binder changed but the difference was consider as limit. For the strength properties, with the using of binder contained 3 types of gels increased the strength. Specimen of FA20SF5 showed the better strength and lower length change of drying shrinkage than other specimens.
