Abstract
Concrete is the most commonly used structural materials, but in concrete construction, its self-weight represents a very large proportion of the total load on the structure, and there are clearly considerable advantages in reducing the density of concrete. This study was carried out to investigate the stress-strain properties of no-fines synthetic lightweight concrete with synthetic lightweight coarse aggregates. The used synthetic lightweight coarse aggregate were two types, one was expanded clay with grading 3~8mm, the other is pumice stone with grading 4.75~10mm. The results of this study were summarized as follows ; The static modulus of elasticity of the synthetic lightweight concrete was
본 연구는 세골재는 사용하지 않고 인공경량조골재로써 팽창점토와 경석을 사용하여 제작된 인공경량골재 콘크리트의 응력-변형율특성을 구명하기 위하여 실시되었으며, 시험을 통하여 얻어진 결과를 요약하면 다음과 같다. 1. 동탄성계수는 인공경량조골재인 팽창점토와 경석을 사용한 경우
