플라이애쉬를 첨가한 고강도 콘크리트의 성질에 관한 실험적 연구 ( An Experimental Study on the Properties of the High Strength Concrete with Condensed Fly Ash )

The purpose of this study is to analyze the mixing condition of high strength concrete according to partial replacement of cement by fly ash. The experimental factors selected in this study are types of sand-aggregate ratio with two levels (40%, 50%), and fly ash contents with five levels (0%, 10%, 20%, 30%), and with partially silica fume (10%). The result of this experiment is the fact that optimum mixing conditions were the case of adding ratio of fly ash 20%, silica fume 10%.
