고로슬래그 치환율이 콘크리트 탄산화에 미치는 영향

Abstract

Recently, it is increasing situations to incorporate blast furnace slag for replacing cement in concrete for cause such as utilization of industry by-product, resource saving, reduction of carbon dioxide. Thus in the study it measured carbonation depth for curing age replace ratio of blast furnace slag and water-binder ratio. it analyzed effect of blast furnace slag on concrete carbonation using accelerated carbonation experiment. Object of this study is to apply for verification of carbonation model using blended cement hydration model and to identify trend of carbonation of concrete in incorporating blast furnace slag. As a result, carbonation reaction indicates faster by increasing replace ratio of blast furnace slag and water cement ratio.
