Abstract
경량기포콘크리트는 경제성 및 시공의 용이성으로 인해 건축물과 성토체로 널리 사용되고 있는 재료이다. 그러나 토목분야에서는 널리 사용되지 않고 있다. 경량기포콘크리트의 재료적인 특성을 파악하기 위한 수많은 연구가 실행되었음에도 불구하고 여전히 미흡한 실정이다. 본 연구에서는 성토재로 사용하기 위한 경량기포콘크리트의 재료적 특성을 파악하고자 실험을 하였다. 물, 모래, 실리카흄의 혼합비를 달리하여 압축강도를 측정하여 서로 비교해보았다. 또한 연구결과를 통해 성토재의 최적배합비 산정과 연구결과를 이용하여 압축강도를 정의하였으며, 설계 시방을 통해 성토재로서의 경량기포콘크리트 적용성을 검증하였다. Lightweight Foamed Concrete is one of the most-used materials for insulation of building and embankment. Since it is economic and workability of construction. However, it is not widely used in civil engineering area. Although several researches were performed to investigate material properties of light weight foamed concrete, it is still remained in unexplored field. In this research, laboratory tests were performed to figure out the material properties of light weight foamed concrete to use embankment. The compressive strengths varying with mixing ratio with water and sand as well as silica fume were compared each other. According to research results, the optimum mixing ratio to use embankment material is suggested and the compressive strength using the results is also defined. The adaptability of light weight foamed concrete as an embankment material is checked with design spec and verified.
