Effects of Filler on Engineering Properties of Permeable Polymer Concrete

충전재가 투수용 폴리머 콘크리트의 공학적 성질에 미치는 영향

This study was performed to evaluate the effects of filler on engineering properties of permeable polymer concrete with unsaturated polyester resin. The following conclusions were drawn; 1. The unit weight was in the range of $1.804{\sim}1.919t/m^3$, the weights of those concrete were decreased 17~22% than that of the normal cement concrete. 2. The highest strength was achieved by stone dust filled permeable polymer concrete, it was increased 17% by compressive, 147% by tensile and 188% by bending strength than that of the normal cement concrete, respectively. 3. The ultrasonic pulse velocity was in the range of 2,722~3,060m/sec, which was showed about the same compared to that of the normal cement concrete. Stone dust filled permeable polymer concrete was showed higher pulse velocity. 4. The water permeability was in the range of $3.076{\sim}4.152{\ell}/cm^2/h$, and it was larglely dependent upon the mix design. These concrete can be used to the structures which need water permeability. 5. The compressive strength, tensile strength, bending strength and ultrasonic pulse velocity were largely showed with the increase of unit weight. But, it was decreased with the increase of water permeability, respectively.
