The test items included slump test, setting time of fresh concrete and the compressive strength, splitting strength, flexible strength, volume change, electrical resistance, permeability and abrasion resistant properties of harden concrete. . The water-cement ratios and anti-permeation admixture proportions were variable in the study .Three water-cement ratios (W/C=0.57, 0.35, and 0.28)and four anti-permeation admixture proportions(0%, 8%, 10%, 12%) were used in test .The normal concrete (adding 0% anti-permeation admixture ) was a control batch. The results show that the volume change and permeability of concrete will be decreased as adding concrete anti-permeation admixture. The mechanical properties and abrasion resistant properties of concrete adding anti-permeation admixture were higher than that of control batch. The results indicate that adding anti-permeation admixture in concrete will make the concrete denser and more durable.
