혼화재를 사용한 산업용 바닥 콘크리트의 물성 검토

Recently, exposed concrete by machinery trowel is generally used in industrial floor such as warehouse. Also, concrete using only the cement has been mainly used except mineral admixture in order to secure surface abrasion resistance. However, in hot weather construction, it is causing a serious problem such as workability inhibition of trowel using only ordinary portland cement. Due to this, it was investigated the effect of application of fly-ash and ground granulated blast furnace slag on properties and abrasion resistance of concrete for industrial floor in this study. The result of this study, it was confirmed that fly-ash and ground granulated blast furnace slag can be used in concrete for industrial floor without affecting significantly the properties of concrete.
