摘　　要：分析目前废弃混凝土再生技术,优化混凝土再生工艺,提出提高再生材料和再生混凝土性能的方法。为提高再生材料性能和废弃混凝土利用水平,在原有再生技术基础上,提出将各类再生材料分别进一步强化处理的再生工艺。试验表明,此种再生工艺解决了目前存在的技术缺陷,在得到再生粗骨料、再生细骨料和再生磨细掺和料的同时,各种再生材料技术指标和再生混凝土使用性能得到提高,增加了再生材料的品种,使废弃混凝土得到全部利用。The recycling methods of wasted concrete and the optimization of concrete regeneration process is analyzed in this paper. To improve the quality of recycled materials and the efficiency of this process, based on the existing regeneration process, the regeneration process to various kinds of recycled materials is optimized. The technical defects have been solved. The recycled coarse aggregate, recycled fine aggregate and recycled mill admixture have been got, meanwhile, all kinds of renewable materials technical indexes and recycled concrete performances have been improved. The varieties of recycled materials are increased, and the waste concrete can be fully utilized.
