An Experimental Study on the Fundamental Properties of Electric Pole Recycled Aggregate(EPRA) and Characteristics of High Strength Concrete by Replacement Ratios of EPRA

폐전주 재생골재의 기초물성 및 대체율에 따른 고강도영역 재생골재 콘크리트의 특성에 관한 실험적 연구

In this study, it was analized and examined fundamental properties of Electric Pole Recycled Aggregate(EPRA) and hardened properties & chemical resistance with H$_2$SO$_4$by replacement ratios of EPRA, and the results are as follows 1) In the case of electric pole recycled coarse aggregate, All fundamental properties are better than that of normal recycled aggregate and both water absorption and amount of crushed loss are with level of natural aggregate 2) As the replacement ratio of electric pole recycled fine aggregate is increased strength development is decreased. but in the case of coarse aggregate, that of it is with level of natural aggregate 3) As the replacement ratio of electric pole recycled fine aggregate is increased chemical resistance is decreased. but in the case of coarse aggregate, that of it is with level of natural aggregate
