| 摘 要： | 研究了不同水胶比条件下,NaOH预处理方式和橡胶掺量对混凝土吸水性、毛细孔隙率、干燥收缩及力学性能的影响。结果表明,掺加经NaOH预处理的橡胶所配混凝土具有更低的吸水率、毛细孔隙率、脆性和更高的抗折强度,预处理对橡胶混凝土上述性能的改性作用与水胶比有关,水胶比较高时改性效果较好。

| Abstract: | The influence of water to binder ratio, rubber pretreated method and dosage to water absorption on the capillary porosity, drying shrinkage and mechanical properties of rubber concrete was studied. The results indicated that the NaOH pretreatment could help improve overall performances of rubber concrete, while its influence is dependent on water to binder ratio of concrete. It is suggested that the improvement of concrete by NaOH pretreatment was enhanced at a higher water to binder ratio. |

| Keywords: | rubber concrete NaOH pretreatment sorptivity toughness water to binder ratio |
