Abstract

In this paper, permeable polymer concretes with unsaturated polyester or vinylester resin content from 5 to 8 weight %, resin-filler ratio of 1 : 1, sand content from 0 to 15 weight % and crushed stone of size 2.5∼10 mm were prepared, and tested for compressive strength, flexural strength and water permeability. The effects of the resin and sand contents on the properties of permeable polymer concrete were discussed. It is concluded from the test results that increase in the strength and decrease in the coefficient of permeability of the permeable polymer concrete arc clearly observed with increasing the resin and sand contents. The permeable polymer concrete showed compressive strength in the range of 170 to 350 kgf/$\textrm{cm}^2$ and flexural strength in the range of 40 to 90 kgf/$\textrm{cm}^2$ at coefficient of permeability from 0.1 to 1.0 cm/sec in this experiment.

본 연구에서는 불포화 폴리에스테르 수지 또는 비닐에스테르 수지를 중량비로서 5~8%, 수지와 충전재의 비 1 : 1, 잔골재량 0~15% 및 입자범위 2.5~10mm의 부순돌을 사용하여 투수성 폴리머 콘크리트를 만든 다음 압축강도, 휨강도 및 투수성을 시험하여 수지와 잔골재의 양이 투수성 폴리머 콘크리트의 물성에 미치는 영향을 구명하였다. 실험결과 수지와 잔골재량이 증가하는데 따라 투수성 폴리머 콘크리트의 강도는 증가하고 투수계수는 저하하였으며, 투수계수 0.1~l.0cm/s를 유지하는 경우 압축 강도는 170~350 kgf/$\textrm{cm}^2$ 그리고 휨강도는 40~90kgf/$\textrm{cm}^2$의 범위를 나타냈다.
