“先消后引”工艺控制聚羧酸减水剂气泡质量的试验研究

Pilot Research on the "Removing-and-adding" Technological Control over the Quality of the Air-cells in the Polycarboxyl Acid Water-reducer

依次使用消泡剂和引气剂对聚羧酸减水剂进行处理,使所生产的混凝土的孔结构质量得以提高,含气量得到控制,达到了预期效果。

By using antifoam agent and air -entraining agent in turn to dispose polycarboxyl acid waterreducer, the quality of the aperture structure of concrete is improved, its air amount contained is controlled and the expected effect is produced.
