摘要 本文通過對引氣劑概述,種類,作用機理和對混凝土的影響及應用進行闡述和分析,并通過試驗對引氣劑對混凝土抗壓強度的影響進行試驗分析驗證。試驗表明:隨著水灰比的增大,引氣劑品種,摻量不變,強度隨著水灰比的增大而降低,三種引氣劑中合成洗滌劑對強度的影響最大,三萜皂甙和松香熱聚物對強度的影響區別不大,不是非常明顯。 關鍵詞:引起劑 混凝土 抗壓強度 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 目錄
