摘　　要：该文以室内试验为基础,研究了虹桥机场大修产生的废弃混凝土再生粗集料的物理性能、力学性能和耐久性能。同时分析了再生细集料的含水率和表观密度特征。从而提出了粗集料密度与吸水率的修正方法。在分析再生集料级配特征的基础上,对再生集料的生产工艺进行了改进。By laboratory experiments,the article studies the physical property,mechanical property and durability property of recycled coarse aggregate from the waste concrete produced in overhaul of Hongqiao Airport,analyzes the moisture content and apparent density of recycled fine aggregate,and puts forward the correction method of coarse aggregate density and water absorption.Based on the analysis of recycled aggregate gradation,the article introduces the improvement of recycled aggregate production process.
