The invention provides a concrete preparation method by recycling waste concrete blocks, which comprises the following steps: (1) crushing the waste concrete blocks to obtain waste concrete particles, washing, airing after washing, soaking with a composite acid solution, washing with clear water, and airing to obtain treated waste concrete particles A; crushing part of the waste concrete particles by adopting a steam kinetic energy mill crushing process to obtain waste concrete powder B; (2) carrying out wet ball milling and superfine grinding on oyster shells, carrying out ball milling, adding waste polypropylene carpet fibers, and carrying out ball milling to obtain a mixture C; (3) mixing and stirring Portland cement and water, sequentially adding the waste concrete particles A and the mixture C, stirring and mixing, finally adding the waste concrete powder B, and stirring to obtain a concrete mixture; and (4) placing the concrete mixture in a mold, and curing to obtain the target concrete. The prepared concrete has good mildew-proof, waterproof and moisture-proof performance.
本发明提供一种废弃混凝土块再利用的混凝土制备方法，包括以下步骤：(1)将废弃混凝土块，破碎得到废弃混凝土颗粒，冲洗，冲洗后晾干，再用复合酸液进行浸泡，清水冲洗、晾干后得到处理后废弃混凝土颗粒A；取部分废弃混凝土颗粒采用蒸汽动能磨粉碎工艺进行粉碎，得到废弃混凝土粉末B；(2)将牡蛎壳经湿法球磨超微粉碎制得，球磨，加入废弃丙纶地毯纤维，球磨，得到混合物C；(3)将硅酸盐水泥和水混合搅拌，依次加入废弃混凝土颗粒A和混合物C，搅拌混合，最后加入废弃混凝土粉末B，搅拌后得到混凝土混合物；(4)将混凝土混合物置于模具，养护后制得目标混凝土。本发明制备混凝土具有良好的防霉、防水、防潮性能。
