Durability in Concrete Containing Limestone Powder and Slag Powder

석회석 미분말과 슬래그 미분말을 혼합한 콘크리트의 내구성

This study is to investigate durability in concrete containing slag powder and limestone power. The variables are the substitution ratio of slag powder and limestone powder. In order to study the effect of slag powder and limestone powder, all mixtures were prepared at a fixed water/cement ratio, slump, and entrained air quantity. When concrete containing slag powder is mixing rate 40%, durability appeared the highest in general. When concrete containing limestone powder is mixing rate 10% in all experiments, the most suitable result appeared.
