為確定引氣劑延緩ASR的機(jī)理，武漢黃引氣劑,設(shè)計(jì)了摻入礦物摻合料(SCM)的混凝土配比,并加入引氣劑,研究了腐蝕溶液中的混凝土試件,包括1.5 a的強(qiáng)度發(fā)展和1 a的堿金屬離子擴(kuò)散濃度,并研究了砂漿棒試件210 d的膨脹率發(fā)展和齡期長(zhǎng)達(dá)6 a的微觀形貌。結(jié)果表明:相較于未使用引氣劑的試件,摻量為0.05%的引氣劑未引起混凝土試件(含氣量5.4%)的強(qiáng)度損失,且有效降低了砂漿棒試件的膨脹率。此外,引氣氣孔成為了ASR產(chǎn)物的儲(chǔ)倉(cāng),若混凝土堿量不變，武漢黃引氣劑,則可控制堿活性骨料周邊的ASR作用程度，武漢黃引氣劑,延緩ASR脹裂的速率,有效改善SCM對(duì)ASR的克制作用。

混凝土中添加引氣劑的作用：可大幅度改善混凝土和易性，可泵性及提高抗?jié)B抗凍等耐久性能，更能有效防止商品混凝土中水泥的二次吸附，減小混凝土坍落度經(jīng)時(shí)損失。由于JDU有較高的減水率，因此可以減少減水劑的摻用，節(jié)約應(yīng)用成本，增加經(jīng)濟(jì)效益。 </p> <p> 引氣劑的功能主要是高減水（比較高減水率可達(dá)10%以上），引氣量適中且泡沫細(xì)密，穩(wěn)定性好，適用于泵送混凝土、防水混凝土、大流動(dòng)性混凝土，更適用于商品混凝土施工。長(zhǎng)沙引氣劑檢測(cè)引氣劑過量使用，會(huì)造成什么后果？</p> -蘇州賽貿(mào)新材料科技有限公司<div style="width:100%;text-align:

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(guó)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)。 </p><p style="text-indent:25px">引氣劑是一種在混凝土或砂漿攪拌過程中引人大量均勻分布的微小封閉氣泡的外加劑。其基本作用表現(xiàn)在以下幾個(gè)方面。改善新拌混凝土拌合物的和易性引氣劑多數(shù)為陰離子型表面活性劑，一般，引氣劑的減水率為6%?9%，盡管不如減水劑那樣大，但也能使新拌混凝土的流動(dòng)性提高不少。改善硬化混凝土的耐久性。硬化混凝土中的微小氣泡能緩沖因水的凍結(jié)而產(chǎn)生的膨脹壓力，減少冰凍破壞，這就提高了混凝土的抗凍性；微小氣泡能切斷硬化混凝土中的毛細(xì)管，減少由于毛細(xì)作用引起的滲透，也就提髙了混凝土的抗?jié)B性。引氣劑的組成有哪些？</p><div
