摘　　要：在混凝土搅拌站生产过程中产生的废料循环利用问题日益突出。针对废混凝土、废浆、废水等主要废料,采用分离-净化-改性工艺路线开展技术研究。研究实验表明,经处理的废混凝土细骨料替代率达35%,压实密度为2.35 g/cm^(3);废浆经改性后替代原生粉煤灰15%,28 d抗压强度达到设计强度96%,商砼站废料循环利用降低了生产成本,推动了绿色建材的发展进程。The recycling of waste materials generated in the production process of concrete mixing plant is becoming increasingly prominent.For the main wastes such as waste concrete,waste slurry and wastewater,the separation-purification-modification process route was used to carry out technical research.The research experiments show that the substitution rate of the treated waste concrete fine aggregate is 35%,and the compaction density is 2.35 g/cm^(3).After the waste slurry is modified,it replaces 15%of the original fly ash,and the 28-day compressive strength reaches 96%of the design strength.
