| 摘 要： | 利用不同品质的3种再生粗骨料,研究了再生粗骨料取代率对混凝土的工作性能、力学性能及干缩性能的影响.结果表明,利用再生粗骨料取代碎石,高品质再生粗骨料可以使碎石混凝土的性能得到改善,而低品质再生粗骨料则降低碎石混凝土的性能,且再生粗骨料取代率不宜超过50%. |
| 关 键 词： | 再生粗骨料取代率 水泥石附着率 抗压强度 弹性模量 干缩 |

| Abstract: | By using three different quality recycled coarse aggregates,this paper presents the effects of the replacement ratio of recycled coarse aggregate on the properties of work,mechanics and drying shrinkage of concrete.The results show that if the recycled coarse aggregate is used to replace gravel,the high-quality recycled coarse aggregate can improve the properties of gravel concrete and the low-quality recycled coarse aggregate can reduce the properties of gravel concrete,and the replacement ratio of recycle... |
| Keywords: | replacement ratio of recycled coarse aggregate adhesion rate of cement mortor compressive strength modulus of elasticity drying shrinkage |
