The invention relates to a production technology for preparing recycled aggregate from waste concrete. The technology comprises the following steps: S1, preprocessing: carrying out jet wetting and epidemic prevention treatment on waste concrete blocks, and then hammering the waste concrete blocks to make the diameter of the hammered concrete blocks less than 50 mm; S2, screening: screening the preprocessed material obtained in step S1; S3, crushing: crushing the screened waste concrete blocks obtained in step S2 to prepare recycled aggregate; S4, reinforcing: reinforcing the recycled aggregateobtained in step S3; and S5, conveying the reinforced recycled aggregate to a storage bin for storage. The recycled aggregate is prepared by preprocessing, screening, crushing, reinforcing, drying and collecting the waste concrete, so that the effective utilization of the waste concrete is realized, the waste of resources is reduced, and the utilization rate of energy is increased. 本发明涉及一种废弃混凝土制备再生骨料的生产工艺，其包括包括以下制备工艺：S1：
