介绍了再生骨料的制备技术,提出了再生骨料的生产工艺,对比研究了再生骨料的性能和再生混凝土的性能。采用先进工艺得到的高品质再生骨料完全可以满足《混凝土用再生粗骨料》(GB/T25177-2001)和《混凝土和砂浆用再生细骨料》(GB/T25176-2001)的要求,制备出满足结构工程需要的再生混凝土,并应用于工程中。 The preparation technology of recycled aggregates is introduced. The production process of recycled aggregates is presented. The properties of recycled aggregates and the properties of recycled concrete are comparatively studied. The high-quality recycled aggregate obtained by the advanced technology can fully meet the requirements of “recycled coarse aggregate for concrete” (GB / T25177-2001) and “recycled fine aggregate for concrete and mortar” (GB / T25176-2001) To meet the structural engineering needs of recycled concrete, and used in engineering.
