摘　　要：采用超细矿渣粉和高性能泵送剂复合配制特细砂水工混凝土,试验结果表明:配制出的特细砂混凝土能满足一般水利工程的质量要求,证明"双掺技术"是可行的。配制特细砂水工混凝土,水泥用量略多于粗、中砂配制的混凝土,但节省了从外地运进大量粗、中砂所耗费的人力、物力;超细矿渣粉的掺加,一方面提高了混凝土的各项性能,另一方面减少了环境污染,维护混凝土材料的可持续发展,具有很好的经济效益和环保效益。superfine sand hydraulic concrete is mixed by means of ultrafine slag powder and high-performance.Pumping agent.it is proved that the quality requirements of the general hydraulic project can be met.double-doped technology is proved feasible.In superfine sand hydraulic concrete,the amount of cement is slightly larger than the coarse sand concrete and medium sand concrete.but a large number of human and money which spends the road from foreign countries to local countries is saved.ultrafine slag powder admixture,on the one hand,the performance of concrete could be improved,on the other hand,the pollution may be reduced.The sustainable development of concrete materials is maintained.it is provided with good economic and environmental benefits.
