초록

In this study mechanical properties of various fiber reinforced permeability concrete mixtures are investigated. Several mixes with fiber kinds(steel fiber, polyprophylen fiber, carbon fiber) and different fiber content(steel fiber : 0.3~0.9vol.%, polyprophylen fiber : 0.1~0.5vol.%, carbon fiber : 0.2~0.7vol.%) were studied. Test results are presented in terms of compressive strength, tensile-flexural strength and load-deflection behavior. The effect of fiber reinforcement does not increase the compressive strength of permeability concrete without fiber. Also, the tensile-flexural strength using various fibers are appeared good strength increase as conventional fiber reinforced concrete. Therefore, use of fiber for permeability concrete is necessary to improve of tensile-flexural properties and deformation performance(toughness).
