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.
