A Fundamental Study on the Properties of Permeable Polymer Concrete

투수성 폴리머 콘크리트의 성질에 관한 기초적 연구

In this study, permeable polymer concretes using unsaturated polyester (UP) resin with binder contents of 6, 7 and 8%, filler-binder ratios of 0, 0.5, 1.0%, and various sand and aggregate contents are prepared, and tested for compressive and flexural strengths, length change and water permeability. The effects of the mix proportioning factors on the strength properties, length change and coefficient of permeability of the permeable polymer concrete are discussed. From the test results, increase in the compressive strength and decrease in the coefficient of permeability of permeable polymer concrete are clearly observed with increasing filler-binder ratio. The permeable polymer concretes having a compressive strength of 9.4~28.3MPa and a coefficient of permeability of 0.12~1.93 cm/s can be produced in the consideration of the mix proportioning factors.
