Abstract |
The permeable polymer-modified concrete has a lot of internal voids, which has more excellent performance in permeability and durability than asphalt and cement concrete. Therefore, the purpose of this study is to ascertain the strength properties of water-permeable polymer concretes with SBR latex and redispersible polymer powder. The water-permeable polymer concretes using SBR latex and redispersible polymer powder with water-binder ratio of 29 ％, polymer-cement ratios of 0, 5, 10, 15 and 20 ％ are prepared, and tested for compressive strength, splitting tensile strength, flexural strength, water permeablility. From the test results, improvements in the strength properties of the water-permeable polymer concretes due to the addition of the SBR latex and redispersible polymer powder are discussed.
