摘要
将建筑垃圾回收利用,处理后重新制备为混凝土块体应用于防洪抗汛,可大幅降低建筑垃圾存放、转运费用,同时降低储备防汛材料的成本,缓解日益突出的石料资源供需矛盾,为发展生态水利、节能水利提供技术支持。基于以建筑垃圾制备防洪块体的关键技术,在此基础上对利用再生混凝土制备防汛块体的成本进行经济分析,评判利用废弃混凝土中的再生粗骨料生产防洪材料产业化的技术经济可行性。
The recycling of construction waste and the preparation of concrete blocks after treatment can be used for flood control,which can greatly reduce the storage and transfer costs of construction waste,reduce the cost of storage of flood control materials,alleviate the increasingly prominent contradiction between supply and demand of stone resources in Jiangsu Province,and provide technical support for the development of ecological water conservancy and energy-saving water conservancy.Based on the key technology of preparing flood control blocks with construction waste,the cost of preparing flood control blocks with recycled concrete was analyzed economically,and the technical and economic feasibility of industrialization of producing flood control materials with recycled coarse aggregate from waste concrete was evaluated.
