An Experimental Study on the Engineering Properties of Flowing Recycled Concrete using Fly-ash

플라이애시를 사용한 유동화재생콘크리트의 공학적 특성에 관한 실험적 연구

As the waste concrete is increased by demolition according to the plan of city-reconstruction and preperation of city-environment etc, the production of waste concrete in the country is being very increased every years. Because the use of recycled aggregate is low, the cases of unlawful reclamation and disuse are increased. These occur the social and economic problems. This experimental study is to investigate the fluidity, compressive strength and durability of flowing recycled aggregate concrete using the river sand and recycled coarse aggregate according to the replacement rate of fly-ash and to present the fundamental data for the using of flowing recycled aggregate concrete.
