摘要:
通过橡胶自密实混凝土的快速冻融试验,研究了不同橡胶取代率下橡胶自密实混凝土力学性能随冻融循环次数的变化规律.试验结果表明:在相同冻融循环次数下,橡胶取代率对橡胶自密实混凝土立方体抗压强度、劈裂强度影响较大,但与取代率不成比例关系;在相同橡胶取代率的情况下,立方体抗压强度及劈裂强度均显示出随冻融循环次数增加而下降的趋势.通过对相关数据的分析研究,给出了橡胶自密实混凝土拉压比随冻融循环次数变化的规律,回归立方体抗压强度、劈裂强度与冻融循环次数间的简明关系式.
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.
