拌合用水中 Ca2+和 Mg2+对混凝土掺用引气剂的影响

摘要

从界面活性作用、起泡作用、稳泡作用三方面,介绍了引气剂的作用机理,并通过试验,分析了水中钙离子对引气剂及其引气效果的影响,提出了降低水中钙镁离子的方法,对控制混凝土的质量起到了重要的作用.%From the interface activity role,popping role,foam stability role three aspects,this paper introduced the mechanism of air-entraining agent,and through the test,analyzed the influence of calcium ion in water to air-entraining agent and its air-entraining effect,put forward the method to reduce the calcium and magnesium ions in water,played important role to control the quality of concrete.
