摘要
对再生混凝土粗骨料分级方法的研究进展状况进行了评述,基于统计学方法深入调查并分析了各国再生粗骨料的评价指标,得出了相关指标的使用频率和数据分布。综合分析了再生粗骨料的分级方法及其实际应用情况,结合我国再生粗骨料分级方法的研究现状,提出了目前存在的一些问题,并对未来再生粗骨料的研究方向进行了展望。
The progress of classification systems of reclaimed concrete coarse aggregate is reviewed. Based on statistical method and thorough investigation, analysis is made on evaluation indexes of reclaimed coarse aggregate in different countries. The frequency of use and data distribution range of correlate indexes is obtained. Comprehensive analysis is made on classification systems of reclaimed coarse aggregate and its practical application, in combination with the current research actuality of classification systems of reclaimed coarse aggregate in China,put forward some existing problems at present, and look into the future of research direction of reclaimed coarse aggregate.
