물시멘트비 및 Bottom Ash 대체율에 따른 콘크리트의 특성에 관한 실험적 연구

An Experimental Study on the Properties of Concrete according to Water-Cement Ratio and Bottom Ash Replacement Ratio

Recently, the coal ash production has been increased by increase of consumption of electric power. So it is important to find a reclaimed place and treatment utility for treating coal ash. Accordingly, in this study we performed an experimental study to compare and analyze the properties of concrete according to W/C and bottom ash replacement ratio. As a result of this study, it was found that the bleeding content was decreased according to decrease of W/C and increase of bottom ash replacement ratio, and the compressive strength of concrete using bottom ash was similar to plain concrete(replacement ratio 0%).
