摘要 本文通过对引气剂概述,种类,作用机理和对混凝土的影响及应用进行阐述和分析,并通过试验对引气剂对混凝土抗压强度的影响进行试验分析验证。试验表明:随着水灰比的增大,引气剂品种,掺量不变,强度随着水灰比的增大而降低,三种引气剂中合成洗涤剂对强度的影响最大,三萜皂甙和松香热聚物对强度的影响区别不大,不是非常明显。 关键词:引起剂 混凝土 抗压强度 Abstract: The summarize、kinds of air entraining admixture and the working mechanism of air entraining admixture in concrete and the influence of air entraining admixture on every property of concrete and something about the apply of air entraining admixture in concrete is deseribed. Though test to validate and analysis the influence of air entraining admixture on compressive strengh of concrete. The test showed that: the same of varieties and content of air entraining admixture, With the increase of water-cement ratio, The compressive strength get Lower . Comparison the three types of air entraining admixture, Synthetic detergent have the most influence with compressive strength.a little difference impact between the Triterpene saponin and Rosin of polymer,that is not very obvious. The Key Words: air entraining admixture concretes compressive strength 目录
