CA砂漿(cementasphaltmortar，簡(jiǎn)稱CA砂漿)。是高速鐵路板式軌道的剛性軌道板與混凝土道床之間的調(diào)平減振結(jié)構(gòu)層材料，它是由水泥、瀝青乳液、砂和多種外加劑組成，經(jīng)水泥與瀝青共同作用膠結(jié)硬化而成的一種新型有機(jī)無(wú)機(jī)復(fù)合材料。CA砂漿的彈性減振性能與其強(qiáng)度密切相關(guān)，其強(qiáng)度大則彈性模量大，減振效果差，而強(qiáng)度小又難以穩(wěn)定支撐軌道和火車，因此適宜的強(qiáng)度范圍對(duì)板式軌道結(jié)構(gòu)的穩(wěn)定極為重要，文獻(xiàn)表明，CA砂漿28d抗壓強(qiáng)度比較合理的范圍是—Mpa。CA砂漿的強(qiáng)度隨著水泥用量和砂用量的增加而增加，隨著瀝青乳液用量的增加而降低；在水泥用量為280—315kg/m3，瀝青乳液用量為435—550kg/m3，砂用量為350—745kg/m3時(shí)可以制備28d抗壓強(qiáng)度在—MPa內(nèi)的CA砂漿，極差結(jié)果表明影響CA砂漿強(qiáng)度的主次因素依次為水泥用量、瀝青乳液用量和砂的用量。隨著外加水用量的增加，CA砂漿硬化體的抗壓強(qiáng)度下降，外加水摻量為50—125kg/m3，都勻五眼砂批發(fā)，即單位用水量：水泥=—，都勻五眼砂批發(fā)，都勻五眼砂批發(fā)，其硬化體28d抗壓強(qiáng)度能滿足—MPa的要求。隨著引氣劑用量的增加，CA砂漿硬化體的抗壓強(qiáng)度下降，引氣劑摻量為0．6‰—1．7‰時(shí)，其硬化體2d抗壓強(qiáng)度能滿足—MPa的要求。

天氣潮濕的沿海地區(qū)或防護(hù)面層砂漿剛施工完不久被雨水淋過(guò)，聚氨酯復(fù)合板的砂漿面泛白現(xiàn)象更是經(jīng)常會(huì)發(fā)生。這些表面泛白是什么原因造成的呢？又怎么能預(yù)防這種現(xiàn)象的發(fā)生呢？砂漿泛白的原因：防護(hù)面層砂漿硬化后，即使比較干燥，但在使用過(guò)程中總會(huì)受到雨水浸泡，當(dāng)水分滲入其內(nèi)部，將其內(nèi)部可溶性物質(zhì)（如NaOH、KOH、Na2SO4、Ca（OH）2等）帶出來(lái)，堿與空氣中的CO2和水分發(fā)生反應(yīng)生成碳酸鹽，與硫酸鹽一起沉淀在表面，且象CaCO3、CaSO4等物質(zhì)不易被雨水沖走，因而牢固地附著在防護(hù)面層表面。當(dāng)有一定濕度時(shí)，空氣中的CO2與水分結(jié)合形成H2CO3,H2CO3與基材表面的Ca（OH）2發(fā)生反應(yīng)，生成CaCO3;H2CO3還會(huì)滲透到基材內(nèi)部與Ca（OH）2化合成Ca（HCO3）2,Ca（HCO3）2也會(huì)隨著表面水分蒸發(fā)被水分從基材內(nèi)部帶出來(lái)，直接結(jié)晶，或者再與H2CO3反應(yīng)生成CaCO3。由于工業(yè)污染，空氣中一般含有一定量的SO2,SO2溶于雨水后形成酸雨，這種酸雨滲入基材內(nèi)部，與基材中的堿性物質(zhì)相結(jié)合并隨著水分遷移到表面結(jié)晶，也會(huì)引起泛白。上述這些白色物質(zhì)的析出結(jié)晶在一定程度上可以增加基材表面的密實(shí)性，但是由于雨水循環(huán)作用，會(huì)將沉積在表面的可溶性的結(jié)晶物沖走，而基材內(nèi)部由于可溶性物質(zhì)的溶出。銅仁抹灰磷石膏砂漿廠抹灰砂漿訂購(gòu)***砂漿廠家直銷,歡迎來(lái)電洽談!</p><div

圖(c)]。由此可見(jiàn)，砂子的空隙率取決于砂料各級(jí)粒徑的搭配程度。級(jí)配好的砂子，不僅可以節(jié)省水泥，還提高了混凝土和砂漿的密實(shí)度及強(qiáng)度。砂的粗細(xì)用細(xì)度模數(shù)Mx表示。細(xì)度模數(shù)越大，表示砂越粗。根據(jù)細(xì)度模數(shù)大小范圍，把砂劃分為粗砂、中砂、細(xì)砂、特細(xì)砂。</p><p>
