| 摘 要： | 再生混凝土粗骨料性能对再生混凝土的物理和力学性能影响很大,很有必要进行科学试验研究。通过对都江堰地震废弃混凝土再生粗骨料的宏观性能试验研究和微观结构形貌分析,得到了再生混凝土粗骨料各宏观特性及相互关系,以及微观结构缺陷对宏观性能的影响。分析得出了砂浆含量高和不可忽略微裂纹多是再生混凝土粗骨料区别普通粗骨料的本质特征,从而为灾区再生混凝土粗骨料的实际应用提供了理论和试验依据。

| Abstract: | It is necessary to conduct scientific experiments on performance of recycled coarse aggregate for its great effects on the physical and mechanical properties of recycled coarse aggregate concrete.By experimental research on recycled coarse aggregate made of earthquake waste concrete from Dujiangyan,the macro properties and their relationships are attained,and the microcrack's characteristics are gotten through microstructure morphology analysis.Moreover,the paper discusses the relationships between the macr... |
