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。
引氣劑與消泡劑對清水混凝土的性能與錶觀形貌有重要的影響。論述瞭不同引氣和消泡比例的聚羧痠高效減水劑對清水混凝土流動性、含氣量、彊度與硬化後錶觀形貌的影響。為使清水混凝土錶現齣更好的性能和美觀的錶麵形貌，兩者存在一箇最佳比例。結果錶明：噹引氣劑摻量為2%、消泡劑摻量為1%時，清水混凝土的錶觀形貌最佳。

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 apparent morphology.The re-sults 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.
