摘　　要：引气剂与消泡剂对清水混凝土的性能与表观形貌有重要的影响。论述了不同引气和消泡比例的聚羧酸高效减水剂对清水混凝土流动性、含气量、强度与硬化后表观形貌的影响。为使清水混凝土表现出更好的性能和美观的表面形貌,两者存在一个最佳比例。结果表明:当引气剂掺量为2%、消泡剂掺量为1%时,清水混凝土的表观形貌最佳。There are important effects of air-entraining admixture and anti-foaming admixture on performance of concrete.It discussed the influence of the different air-entraining and anti-foaming ratio in polycarboxylate superplasticizer on concrete fluidity, air content and strength.The optimal ratio between the two made plain fair-faced concrete showed better performance and apparem morphology.The re- suits showed that, when air-entraining admixture dosage was two over ten thousand and anti-foaming dosage was one over ten thousand, the apparent morphology of fair-faced concrete was the best.
