- Abstract:
- Through the freezing and thawing tests,the influence of replacement rate of rubber on mechanical properties of rubberized self-compacting concrete (RSCC) under different cycle times of freeze-thaw were studied.The results showed that the replacement rate of rubber had great influence on cubic compressive strength and split strength of RSCC under the same freeze-thaw cycle time,but not in proportional relation;cubic compressive strength and split strength of RSCC under the same replacement rate of rubber decreased with the freeze-thaw cycle times increasing.Based on the analysis of the test data,the change law between tensioncompression ratio and freeze-thaw cycle times was given,and the relevant simple formula were regressed between cubic compressive strength,split strength and freeze-thaw cycle times.This study could serve as a reference for durability of RSCC under freezing and thawing environment.
