董箐水电站水工高性能混凝土应用技术研究

摘要

Through experimental study on contrast polycarboxylic high range water reducer and naphthalene superplasticizer in Dongqing Hydropower Station, the conclusion which is that polycarboxylic high range reducer can greatly reduce water using and improve fly ash content and mechanical properties and durability was drawn. This paper provided data for improving the application of polycarboxylates high range concrete in hydraulic structures.%通过对比聚羧酸高效减水剂和萘系减水剂在董箐水电站地下厂房中的试验研究，本文得出聚羧酸高效减水剂极大地降低了用水量，提高了高性能混凝土粉煤灰掺量，且力学性能和耐久性能优异的结论，为推动聚羧酸高性能混凝土在水工建筑物中的应用提供了科学依据。
