聚羧酸高效减水剂对粉煤灰混凝土性能的影响及其应用

The Effect of Polycarboxlic Series of High Performance Water ReducerOn Fly Ash Concrete′Property and its Application

探讨聚羧酸系高效减水剂的作用机理,分析其在粉煤灰混凝土中应用的技术特点,为新型外加剂的推广提供借鉴和指导.工程实践表明:聚羧酸系高效减水剂具有水泥相容性好、减水率大、坍落度损失小、与粉煤灰适应性强等优点,具有良好的技术经济效益.

This paper discusses its action principle and analyses its technical characters when polycarboxlic series of high performance water reducer used in commercial concrete. Experience shows that polycarboxlic series of high performance water reducer owns some advantages such as much reducing water、better keeping slump and better fixing to cement. It has better market value in technology and economy.
