조경 포장용으로 사용가능한 친환경 콘크리트의 물리ㆍ역학적 특성연구

Physical and Mechanical Properties study for Environmental Friendly Concrete of Landscape Architecture Pavement

The mechanical properties appeared at the granite soil-concrete mixed with PP fiber(1kg/m³, 3kg/m³, 5kg/m³) are compared with normal concrete and wire mesh one and evaluated. Compressive strengths and flexural strengths of the concretes with PP fiber and without the fiber are appeared almost alike. If examine load resistance ability by PP fiber mixing amount increase, it could know that the increase of fiber mixing amount improves load resistance ability and the toughness index is increased. While normal concrete is broken at the same time with crack, fiber mixed concrete stand in flexure load continuously after crack occurrence. In compare with wire mesh embeded concrete, wire mesh mixed concrete stands in some degree in flexure load by wire mesh crack occurrence and the test piece was broken at the same time. But, it could know that the PP fiber mixed concrete resist continuously to flexure load in bigger displacement.
