The Effects of Recycled Aggregate Shape on Compressive Strength and Slump of Recycled Concrete

재생골재 입형이 재생골재콘크리트의 압축강도와 슬럼프에 미치는 영향

The efforts have improved the absorbtion that in order to high the quality of recycled aggregates, and the shape. For the shape of recycled aggregates, the shape of usually aggregates can affect the strength of concrete in an indirect way. So that, in the study, effects is investigated the shape of recycled aggregates that affects the compressive strength and slump. In the result, the a improved shape have a beneficial effect on compressive strength and slump for of a high quality recycled aggregate, and these appear a larger effects in unit water ; $175kg/m^3$ or specified strength ; 24MPa.
