Preparation method of high-strength recycled aggregate concrete
The invention provides a preparation method of high-strength recycled aggregate concrete, and belongs to the technical field of recycled aggregate concrete.The preparation method of the high-strength recycled aggregate concrete comprises the steps that recycled aggregate is mechanically strengthened; collecting associated stone powder generated in the recycled aggregate mechanical strengthening step; taking the mechanically strengthened recycled aggregate as fine aggregate, taking natural aggregate as coarse aggregate, and determining the ratio of the fine aggregate to the coarse aggregate, namely the aggregate ratio; taking the collected associated stone powder as a mineral admixture, determining the ratio of the associated stone powder to cement powder, and doping the associated stone powder into the cement powder; then determining the ratio of the cement powder mixture to water, namely the ratio of concrete slurry; the mechanical property of the recycled aggregate can be improved, and meanwhile, the problem of resource utilization of the associated waste powder is solved.
本发明提供了一种高强再生骨料混凝土制备方法，属于再生骨料混凝土技术领域，该高强再生骨料混凝土制备方法包括对再生骨料进行机械强化；收集所述再生骨料机械强化步骤中产生的伴生石粉；将进行机械强化后的再生骨料作为细骨料，采用天然骨料作为粗骨料，并确定所述细骨料与所述粗骨料之间的配比，即骨料配比；将收集的伴生石粉作为矿物掺合料，确定所述伴生石粉与水泥粉的配比后，将所述伴生石粉掺入所述水泥粉中；得到水泥粉混合物，然后确定所述水泥粉混合物与水的配比，即混凝土浆体配比；本发明能够在提高再生骨料的力学性能的同时解决伴生废粉的资源化利用问题。
