引气剂对混凝土性能的影响

Effect of Air Entraining Agent on Properties of Concrete

本文论述了引气剂的作用机理，重点探讨了混凝土抗压性、持久性以及新搅拌混凝土的易溶性、含气量等受到引气剂的影响。通过试验，将其应用于津保铁路子牙河特大桥承台的施工，指出了引气剂是高性能混凝土的必备外加剂。

This paper discussed the mechanism of air entraining agent, focusing on the ability against press of concrete, durability and the solubility and air volume of new stirred concrete affected by air entraining agent. Through the experiment, the air entraining agent was applied to the pile cap of huge Ziya River Bridge between the railway from Tianjin to Baoding and the author pointed out the air entraining agent is a necessary admixture to concrete of high performance.
