摘要

摘要: 随着我国城镇化改造和城市建设步伐的加快,建筑垃圾与日俱增,带来了城市发展与环境恶化的矛盾。再生骨料(Recycled Aggregate,即RA)的使用可以在一定程度上缓解对环境产生的污染,但其来源存在质量品质稳定性差、离散性大等缺点。通过对不同来源、不同服役寿命期的废弃混凝土进行了共计112组粗骨料性能试验和12组细骨料性能试验,对比分析了再生骨料与天然骨料各项指标之间的差异,并对砖粒含量对再生粗骨料性能的影响做了压碎值指标性能试验,为研究再生骨料性能及适应于当地的分级标准提供一定的参考依据。

Abstract: With the transformation of China's urbanization and accelerated pace of urban agglomeration,increasing construction waste has brought the conflict between the development of a city and its environmental degradation. The use of recycled aggregate( RA) can mitigate to a certain extent the pollution on the environment. Because the source of RA can cause poor stability in its quality,large dispersion and other shortcomings. By three different sources and different service life of the waste concrete for a total of 112 groups of coarse aggregate performance tests and 12 sets of fine aggregate performance tests,comparative analysis of the differences of indicators between recycled aggregate and natural aggregate was done,and a crushing value performance test was also made to analyse the effect of brick particles content on the behavior of recycled coarse aggregate. Which provided a reference for the research on properties of recycled aggregate and the local grading standards suitable for local conditions.
