| 摘 要： | 研究了不同砂率的透水混凝土的塑性与初期收缩性能,同时还对比研究了同强度等级的透水混凝土与普通混凝土的收缩特性.由试验结果可见,砂率增加可明显降低透水混凝土的塑性和初期收缩,对于透水混凝土与普通混凝土,在塑性阶段和硬化初期,前者的收缩大于后者,而在硬化后随着龄期(14d后)的增长,后者的收缩超过前者.

| Abstract: | The plastic and early shrinkage of pervious concrete with different sand percentages were studied,and the shrinkage character of the concrete at various ages were discussed in contrast to the ordinary concrete as well.The conclusions can be drawn that an increase in sand content can reduce the plastic and early shrinkage of pervious concrete obviously;in initial days of curing age,the shrinkage of the pervious concrete with sand free appeared to be higher than that of the ordinary concrete,however,after 14d... |
