摘　　要：利用城市污水处理厂的沉淀污泥为主要成分可配制水下不分散剂.试验结果表明,掺入水下不分散剂可在水中浇筑C30强度等级的水下不分散混凝土,其抗渗等级可达W10～W12,并且水下不分散混凝土的各种性能既可满足工程要求,又能废物再生利用、降低原材料成本,减少了对环境的污染.An underwater anti-washout agent can be made of the settling sludge of effluent plants. Experiments＇ results show that underwater anti-washout concrete of strength of C30 can be cashed by using the anti-washout agent, and the grade of permeability-resistance can be of W10 - W12. Not only the properties of the underwater anti-washout concrete can meet the project＇s demands, but also the material costs can be cut by waste reuse and the environment pollution reduced.
