Carbonation Depths of the Concrete Using Coal Gasification Slag Fine Aggregates Depending on Premix Type Cements

CGS를 잔골재로 활용한 콘크리트의 사전혼합시멘트 종류별 탄산화 특성

In this study, concrete durability was reviewed before CGS, a by-product generated from IGCC, was used as a fine aggregate for concrete. The characteristics of concrete and effect on carbonization according to the type of pre-mixed cement and the CGS substitution rate were analyzed. As a result of the analysis, the depth of carbonation according to the pre-mixed cement types increased by up to 52%, and the carbonation resistance tended to be similar overall when CGS was used as a fine aggregate.
