Permeability, Strengths and Durability of Fiber Reinforced Porous Polymer Concrete Using Recycled Aggregate for Permeable Pavement
Research on permeable pavement like asphalt and concrete pavement with porous structure has been increasing due to environmental and functional need such as reduction of run off and flood, and increase and purification of underwater resource in Korea. This study was performed to evaluate permeability, strengths and durability of porous polymer concrete (PPC) using recycled aggregate that is obtained from waste concrete. Also, 6mm length of polypropylene fiber was used to increase toughness and interlocking between aggregate and aggregate surrounded by binder. In the test results, regardless of kinds of aggregate and fiber content, the compressive strength and permeability coefficient of all types of PPC showed the higher than the criterion of porous concrete that is used in permeable pavement in Korea. Also, strengths of PPC with increase polypropylene fiber content showed slightly increased tendency due to increase binder with increase of fiber content. In durability test for sulfuric acid, and freezing and thawing, PPC with fiber after 28 days of immersion in H2SO4 solution and 300 cycles of freezing and thawing didnt occur to any weight change and any decrease of relative dynamic modulus.
