The invention relates to a processing technology of concrete doped with waste concrete blocks. The processing technology comprises the following steps: S1, pretreating waste concrete blocks to obtainconcrete fine blocks; S2, decomposing the surface of the concrete fine block to obtain a surface-modified concrete fine block, and forming a strong acid salt layer on the surface of the concrete fineblock; S3, preparing the coarse aggregate to prepare the coarse aggregate for later use; S4, preparation of a cementing material: preparing the cementing material for later use; and S5, preparing concrete, namely adding the coarse aggregate prepared in the step S3, the cementing material prepared in the step S4, an additive and water into a concrete stirrer according to a weight ratio, and performing stirring for 10-20 minutes at the stirring speed of 200-400r/min, thereby obtaining the finished product concrete. In the processing technology, the waste concrete blocks and the waste rubber particles are recycled as raw materials, and, the comprehensive performance of the concrete is improved.
本发明涉及一种掺杂废弃混凝土块的混凝土加工工艺，包括有以下工艺步骤：S1，废弃混凝土块的预处理，制得混凝土细块；S2，混凝土细块表面的分解处理，制得表面改性后的混凝土细块，混凝土细块的表面形成强酸盐层；S3，粗骨料的制备，制得粗骨料以备用；S4，胶凝材料的制备，制得胶凝材料以备用；S5，混凝土的制备，将步骤S3制得的粗骨料、步骤S4制得的胶凝材料、外加剂和水按重量配比加入至混凝土搅拌器，混凝土搅拌器的搅拌速度为200～400r/min，搅拌时间为10～20min，即制得成品混凝土。本发明的加工工艺中回收再利用了废弃混凝土块和废旧橡胶颗粒作为原材料，同时改善混凝土的综合性能。
