Abstract

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.

최근 물류창고 등의 산업용 바닥은 기계식 미장에 의해 마감을 하는 노출콘크리트가 일반적인 추세이며, 표면 내마모성 등의 확보를 목적으로 시멘트만을 사용하는 배합이 주로 활용되고 있다. 그러나 하절기 공사시 시멘트만을 사용할 경우 응결이 촉진되어 미장작업에 문제를 초래하는 사례가 발생되고 있다. 이에 본 연구에서는 바닥용 콘크리트에 혼화재료로 플라이애시 및 고로슬래그 미분말을 적용할 경우 콘크리트 물성 및 내마모성에 미치는 영향을 검토하였다. 검토 결과 산업용 바닥 콘크리트에서 콘크리트의 물성에 크게 영향을 미치지 않으면서 플라이애시 및 고로슬래그 미분말을 일부 혼입하여 사용할 수 있다는 것을 확인할 수 있었다.
