Preparation process of recycled concrete aggregate
The invention discloses a preparation process of recycled concrete aggregate, and relates to the technical field of concrete. The preparation process comprises the steps of S1, conducting pretreatment, specifically, hammering collected concrete blocks, and removing steel bars and various impurities in the concrete blocks; S2, conducting crushing treatment, specifically, respectively carrying out primary crushing treatment and secondary crushing treatment on the pretreated concrete blocks; S3, conducting screening treatment, specifically, screening the crushed concrete blocks to obtain recycledconcrete aggregate particles meeting the particle size requirement; and S4, conducting grading treatment, specifically, conducting wind power grading treatment on the recycled concrete aggregate particles obtained after screening treatment so as to remove micro powder with the small particle size. By adopting the preparation process of the recycled concrete aggregate, the quality of the recycledconcrete aggregate can be improved, the recovery rate of waste concrete is greatly increased, the economy is high, and the operation is convenient.
本申请公开了一种再生混凝土骨料的制备工艺，涉及混凝土技术领域。该制备工艺包括以下步骤：S1，预处理，对收集回来的混凝土块进行锤击，并除去其中的钢筋和各种杂质；S2，破碎处理，对预处理后的混凝土块分别进行初步破碎处理和再次破碎处理；S3，筛分处理，对破碎处理后的混凝土块进行筛分，得到复合粒径要求的再生混凝土骨料颗粒；S4，分级处理，对筛分处理后得到的再生混凝土骨料颗粒进行风力分级处理，以除去粒径较小的微粉。采用本申请的再生混凝土骨料的制备工艺，能够提高再生混凝土骨料的品质，大幅度提高废弃混凝土的回收率，经济性高，操作方便。
