Effect of the Use of Recycled Coarse Aggregate with the size of 5~13mm on the Fundamental Properties of the Concrete

5~13 mm 순환 굵은 골재 혼합 사용이 콘크리트의 기초적 특성에 미치는 영향

Consider about aggregate's price, coarse aggregates from 13 to 25mm were widely used in ready mixed concrete company. But if only use 13 to 25mm aggregates in the concrete, gap grading problem would be occurred. When recycled aggregates from 13 to 25mm was used, continuous grading would increase the durability and strength for the concrete, meanwhile the construction waste materials would also be reused. In this paper, 5-13mm recycled aggregates was utilized, to analyse the fundamental properties for concrete, strength has been tested to evaluate the quality and reusing effect of the recycled materials.
