The Properties of High Flowing Concrete with the Kind and Content of Limestone Powder

석회석 미분말의 종류 및 함유율 변화에 따른 고유동 콘크리트의 특성

In this paper, the application of limestone powder, which produced by being gathered electrically in the process of manufacturing of cement, to high fluidity concrete are investigated. According to the experimental results, especially, high viscosity and the loss of air content are accomplished by applying limestone powder as the partial substitution of fine aggregates. In case of hardened concrete, high compressive strength can be achieved by using limestone powder.
