| 摘 要： | 设计并完成了26组混凝土配合比试验，系统地研究了再生混凝土的劈裂抗拉强度与水灰比、粗骨料取代率以及砂率之间的关系。通过试验对比分析认为：再生混凝土的劈裂抗拉强度与再生粗骨料取代率的关系密切．再生混凝土的劈裂抗拉强度与水灰比、砂率的关系不尽相同。最后结合试验结果对再生混凝土的配合比设计提出了建议。

| Abstract: | 26 kinds of mixture ratio for concrete were designed and performed. We studied the relationships between the construction performance of concrete, split - tension strength and the water / cement ratio,replace- ment ratio of recycled aggregate,sand rate. The results indicated that the recycled coarse aggregate replace- ment ratio has a remarkable influence on the split - tension strength of recycled aggregate concrete. The rela- tionships between the split - tension strength,the water / cement ratio and sand... |
