소 도로포장 재료로서 재생콘크리트의 역학적 특성
Mechanical Characteristics of Recycled Concrete as a Pavement Material for Low-Volume Road
초록
본 연구는 소도로 포장용 재료로서 재생콘크리트의 역학적 특성과 성능을 규명하였다. 재생콘크리트는 굵은 골재의 반을 재생골재로 대치하여 제조되었고 이와 함께 천연 잔골재와 유동화제 그리고 플라이애쉬(각각 시멘트 중량의 0.8% 및 5%)가 사용되었다. 실험을 통하여 재령28일 재생콘크리트의 휨강도, 압축강도, 탄성계수 및 파괴인성은 약
This study evaluated mechanical characteristics and performance of recycled concrete
as a pavement material for use in low volume road. The recycled concrete was prepared
by replacing a half of coarse aggregate with recycled coarse aggregate. Natural sand
from a source was used as fine aggregate together with admixtures, such as plasticizer
and fly ash (0.8% and 5% by wt. of total binder, respectively). From experimental
evaluation. it was found that flexural strength. compressive strength, elastic modulus
and fracture toughness of recycled concrete at 28 days were approximately
