The invention provides concrete based on solid waste cyclic utilization and a preparation method, and relates to the technical field of concrete.The preparation method comprises the steps that S1, waste concrete is collected and crushed to serve as aggregate, and cleaning and drying are conducted; s2, mixing the Portland cement with the aggregate to form a mixture; s3, waste plastic is collected, mixed melting treatment is conducted, plastic fibers are prepared, and corrosion resistance and strength modification are conducted; and S4, mixing the modified fibers into the mixture, uniformly stirring, adding water and a plasticizer, and mixing to form the concrete material. The recycled waste concrete is processed into the fine aggregate and the coarse aggregate to replace the original stones and river sand, so that natural resources are saved, the material cost can be reduced and the economical efficiency of the concrete can be improved on the basis of completing the recycling of the waste building materials.
本发明提供了基于固废循环利用的混凝土及制备方法，涉及混凝土技术领域，包括，S1：收集废弃的混凝土，并进行破碎作为骨料，清洗并干燥；S2：将硅酸盐水泥与骨料进行混合，形成混合料；S3：收集废弃塑料，混合熔融处理，制备塑料纤维，并且进行耐腐蚀及强度改性；S4：将改性纤维混入混合料中，搅拌均匀，并且加入水及塑化剂，混合形成混凝土材料。基于回收的废弃混凝土，将其加工生成细骨料及粗骨料，以取代原有的石子及河砂，在能够在完成废弃建筑材料回收的基础上，节省自然资源，也能降低物料成本，提高混凝土的经济性。
