    摘 要:為研究機場道面施工工藝和引氣劑品種對混凝土氣泡特征參數的影響規律,采用4種國內常用的引氣劑配置了含氣量為6%的機場水泥混凝土。試驗結果表明,經排式振搗機振搗后,混凝土的含氣量大幅度降低,氣泡總數和小孔徑氣泡個數顯著增加;摻不同品種引氣劑的混凝土經機場道面施工后,其氣泡特征參數有較大的差異;優質引氣劑經施工后在混凝土中形成大量小孔徑氣泡,氣泡間距系數明顯降低。 Abstract: In order to study the effect of airport pavement concrete construction and air entraining agent on air void characteristic parameters, four types of air entraining agent which are frequently used in China are adopted, and the airport cement concrete with air content of 6% is tested. The results show that air content in concrete decreases greatly while the total air number and the tiny air void number increase remarkably after HPZ vibration. Concrete with different air entraining agent lead to quite different air void characteristic parameters after airport concrete construction. Air void spacing factor decreases greatly after HPZ vibration and lots of tiny air voids are entrained in concrete with good quality air entraining agent.
