摘要：
The variation law of relative dynamic modulus (Dm), corrosion resistance coefficient of compressive strength (Kf) and mass loss rate (Ml) of the rubberized self-compacting concrete (RSCC) was investigated using the experimental method for sulfate attack in dry-wet cycles. The results show that Dm and Kf for RSCC specimens first increase but then decrease with increasing number of dry-wet cycles. At the same water to binder ratio, Dm and Kf decrease with the increase of the rubber particles substitution (substituting sand with the same volume) at the end of experiment, whereas increase in the same strength grade. Ml of RSCC increases rapidly in the initial dry-wet cycles. At the same water to binder ratio, Ml increases with increasing rubber particles substitution at the end of experiment, whereas decreases in the same strength grade. As the rubber particles substitution reaches 10%, the comprehensive performance of RSCC is perfect. The improved prediction model can effectively reflect the relationship between Kf and the rubber particles substitution of RSCC. © 2017, Editorial Department of Journal of Building Materials.
