摘　　要：为研究橡胶颗粒及再生碎石掺量对自密实混凝土抗水渗透性能的影响,以C40自密实混凝土试件为基准,对不同掺量组合的自密实橡胶再生混凝土进行抗水渗透性能试验。试验结果表明;橡胶颗粒掺入能有效改善混凝土抗渗性能,当再生碎石掺量为30%,橡胶颗粒掺量为10%,混凝土抗渗性能优与基准组;根据混凝土的抗渗性能试验结果,工程中较为合适的再生碎石掺量为30%,橡胶颗粒掺量为10%。To study the effect of rubber particles and recycled coarse aggregate content on the water permeability resistance of self-compacting concrete,water permeability resistance tests of selfcompacting rubber recycled concrete with different content combinations were tested with C40 selfcompacting concrete specimens as the benchmark..The experimental results indicate that the addition of rubber particles can effectively improve the impermeability of concrete.When the content of recycled coarse aggregate is 30%and the content of rubber particles is 10%,the impermeability of concrete is superior to the benchmark group;According to the test results of the impermeability performance of concrete,the appropriate amount of recycled coarse aggregate in the project is 30%,and the amount of rubber particles is 10%.
