순환골재를 사용한 도로포장용 투수 콘크리트의 역학적 특성

This study investigated the mechanical properties of permeable concrete using recycled aggregate. The results from the study are summarized as follows. In terms of compressive strength according to grade combinations, the use of low-grade recycled aggregate with 2.5 mm showed the highest compressive strength in combination. The bending strength at the age of 28 days showed a higher strength with multiple grade combination compared to single grade case. In both cases, however, the strength was measured as below 3 MPa, which implies that further study is necessary in the direction to enhance bending strength. It is also indicated that better permeability coefficient were related to higher grade of recycled aggregate.
