| Abstract |
This study was performed to determine the effects of filling materials on the physical properties of permeable polymer concrete. The filling materials were ground calcium carbonate, ground granulated blast furnace slag and fly ash. In this experiment, permeable polymer concrete mixtures with unsaturated polyester resin contents from 5 to 7 weight %, filler/resin ratio of 0~2.0 and crushed coarse aggregate passing 15 ㎜ sieve were prepared and coefficient of permeability, void ratio, compressive strength and flexural strength were tested. As the test results, increase in the strength and decrease in the coefficient of permeability of the permeable polymer concrete were generally observed with increasing the resin contents and filler/resin ratio. The compressive and flexural strength of the permeable polymer concrete were in the range of 8.0 to 35.0 ㎫ and 2.0 to 9.0 ㎫ respectively and the highest strength was shown at the mixtures with 7 weight % unsaturated polyester resin contents, 2.0 ratio of filler/resin and filler of ground calcium carbonate. On the other hand, in the level of 20 ㎫ compressive strength, the mixtures with filler of fly ash was shown as the most economic permeable polymer concrete. |
