摘要
望虞河立交上程是治理太湖的关键性的防洪控制工程，因其混凝土工程量大、工期短而采用集中搅拌、泵送浇筑混凝土施工工艺。为此，从几种混凝土外加剂的性能试验对比中，优选了ＡＴ缓凝高效减水剂增大混凝土的流动性能，达到顺利泵送的目的，并取得了较好的技术经济效果。
The network of waterways progect of Wang Yu River is a critical preventing flood project for bamessing Tai Hu Lake.A construction technology of pumping concrete was adopted due to there are heavey concrete pouring and urgent time limit for the prozect.Therefore,a series of experiments on performances of several water-reducing admixtures were developed,and a optimun AT type set retarding and superplasticizer admixture was selected since its superior function for pumping aid, and a good technical economic results hare been achieved.
