比較早取得技術(shù)**的混凝土引氣劑是文沙樹脂，它是木松香精制過程中的一種副產(chǎn)品。我國50年代研制了以松香熱聚物為主要成分的引氣劑，接著進(jìn)行了松香皂、OP乳化劑和801-2等引氣劑的研究應(yīng)用工作。目前市場(chǎng)上銷售的引氣劑主要有PC-2型引氣劑、CON-A型引氣劑、KF微沫劑和SJ-1、SJ-2引氣劑等。 </p> <p> 引氣劑摻量非常小，卻能因使混凝土在攪拌過程中引氣而大幅度改善混凝土的抗凍融循環(huán)方面的耐久性，應(yīng)用在道路、橋梁、大壩和港工等方面，提高了它們的使用壽命，因此，它是一種非常重要的外加劑。所以，引氣劑問世至今，仍然被看作是混凝土材料科學(xué)發(fā)展過程中的一大重要發(fā)現(xiàn)。防水砂漿**引氣劑。</p><div
