| 摘要: |
| 分别用平板法及圆环法测试研究了不同代砂率的橡胶砂浆在塑性阶段及硬化早期阶段的收缩开裂性能.试验结果表明,橡胶砂浆具有较好的抗塑性收缩开裂和抗硬化早期干缩开裂性能,在砂完全被橡胶颗粒代替时,橡胶砂浆不产生可见的收缩裂缝. |

| Abstract: |
| Properties of anti-cracking of rubberized mortar were studied at plastic stage and hard stage by the method of board and ring devices respectively.The experimental results indicate that rubberized mortar has good anti-cracking properties at both stages.There is no cracks occurred when sands are completely replaced by crushed rubbers. |
| Key words: rubberized mortar,dry shrinkage,plastic shrinkage,crack |
