| 摘 要： | 通过对不同橡胶掺量、养护方式和加载历史条件下橡胶混凝土试件在不同应变率下的抗压试验，表明橡胶混凝土的抗压强度随应变率的提高而增加，随橡胶掺量的增加而有所降低。橡胶混凝土的率应变抗压强度对养护条件比较敏感，加载历史引起的混凝土内部损伤会降低橡胶混凝土强度。

| Abstract: | The effect of rubber contents, cure conditions and loading history on compressive strength of rubberized concrete under different load velocity was studied. The fracture mechanism of CRC is analyzed. The test results show that the compressive strength of rubberized concrete increases with the increase of strain rate, and decreases with the increase of rubber contents. The compressive strength is sensitive to cure conditions. The moisture contents can enhance the strain rate sensitivity of rubberized concrete in compression. The internal damage of concrete from loading history reduces the strength of rubberized concrete. |
