| 摘 要： | 设计并完成了20个混凝土配合比试验,系统地研究了再生混凝土的抗压强度与水灰比、粗骨料取代率以及龄期之间的关系。通过与普通混凝土试验对比分析认为:再生混凝土的抗压强度随龄期的发展规律类似于普通混凝土;再生混凝土的抗压强度与再生粗骨料取代率的关系密切;再生混凝土的抗压强度与水灰比的关系不尽相同。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: | 20 kinds of mixture ratio for concrete were designed and performed. We studied the relationships among recycled aggregate concrete's compressive strength, the water/cement ratio,replacement ratio of recycled aggregate and age. The results indicated that the development for the compressive strength of recycled aggregate concrete is the same as that of normal concrete. The recycled coarse aggregate replacement ratio has a remarkable influence on the compressive strength of recycled aggregate concrete. The rel... |
