An Experimental Study on The Application of Construction of Recycled Aggregate Concrete (part2, in the hardened concrete)

재생골재 콘크리트 구조체 적용성에 관한 실험적 연구(제2보, 경화 콘크리트의 성상을 중심으로)

Critical shortage of natural aggregate for production of concrete is developing in many urban area. At the same time increasing quantities of demolished concrete form deteriorated and obsolete structures are generated as a waste material in the same areas. The reuse of a waste concrete may settle the problems of environmental pollution and shortage of adquate aggregate, Therefore, this study is to reuse a waste concrete as aggregate for concrete, It is the purpose of this present study to investigate and analyze how the addition rates of superplasticizer and curing condition affect the properties of fresh and hardened recycled aggregate concrete comparing with those of ordinary concrete and crushed stone concrete.
