style="font-size:14px;">我國泡沫混凝土發(fā)展并不晚，僅次于歐洲。1950年，前蘇聯(lián)**就開始向中國推廣泡沫混凝土技術(shù)。1952年，中國科學(xué)院土木建筑研究所成立了以黃蘭谷為首的泡沫混凝土試驗(yàn)中心，開始了中國泡沫混凝土的正式試制。研制出性能優(yōu)越的蒸壓加氣泡沫混凝土制品，并被使用在建筑保溫等實(shí)際工程中，但由于歷史原因其發(fā)展受到阻礙。</span> </p> <p> <span style="font-size:14px;">近年來，泡沫混凝土在我國重新獲得興盛發(fā)展，再加上歐洲泡沫混凝土現(xiàn)澆技術(shù)的傳入，泡沫混凝土被普遍使用在保溫現(xiàn)澆兩大應(yīng)用領(lǐng)域，在建筑節(jié)能、建筑工程回填及巖土工程等各個(gè)方面運(yùn)用普遍，成效明顯。</span> </p> <p> <span style="font-size:14px;">目前，我國泡沫混凝土年生產(chǎn)總量已突破600萬m3，其中，現(xiàn)澆類約占生產(chǎn)總量80%以上，其他約20%。</span> 昆明混凝土價(jià)格一般是多少昆明輕質(zhì)發(fā)泡混凝土哪家好？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="云南泡沫輕質(zhì)混凝土報(bào)價(jià),混凝土" src="https://tyunfile.71360.com/UploadFile/yongxinjiancai2020/637324813510234375/7455264.png"></div><p> <span style="font-size:14px;">傳統(tǒng)的處理這些冒頂空洞的方法是用人工搭設(shè)木垛或采用聚胺脂類材料化學(xué)加固。木垛施工速度慢，材料消耗大，木垛與頂板接觸面小，控制作用差，且作業(yè)十分危險(xiǎn)。化學(xué)加固存在成本高、易發(fā)熱著火等弊端。采用泡沫混凝土充填冒頂空洞可克服這些缺點(diǎn)。通過調(diào)節(jié)發(fā)泡倍數(shù)以及改變水灰比來調(diào)節(jié)泡沫混凝土抗壓強(qiáng)度，大可以提高到13MPa左右。當(dāng)材料單向受壓達(dá)到屈服極限后，隨著變形的增加，材料仍能保持較高的承載能力。因材料結(jié)構(gòu)是閉孔型的，故具有良好的氣密性。這種利用泡沫水泥充填冒落空洞的方法可使處理冒頂空洞的工作實(shí)現(xiàn)機(jī)械化，施工安全，速度快，能增大對(duì)空洞壁的支撐，防止冒頂范圍繼續(xù)擴(kuò)大，改善支架與圍巖的相互作用，并可防止空洞內(nèi)有害氣體積聚，防止發(fā)火，是一項(xiàng)有許多優(yōu)點(diǎn)的新技術(shù)。</span> </p> <p> <br /> </p> <p> <br /> </p><p> <span style="font-size:14px;">泡沫混凝土是一種新型的混凝土材料，近年來，在全球范圍內(nèi)得到了大力的推廣和普遍的應(yīng)用。究其原因，主要是因?yàn)榕菽炷辆哂泻芏嗔己玫男阅?，能夠適應(yīng)工程建設(shè)的不同需要。現(xiàn)簡(jiǎn)單介紹如下：</span> </p> <p> <span style="font-size:14px;">一，質(zhì)地很輕。表觀密度在160kg/m3左右的泡沫混凝土質(zhì)地非常輕，目前在公路工程領(lǐng)域開始推廣并使用。</span> </p> <p> <span style="font-size:14px;">由于具有較小的荷載，它可以減少約 1/4 的自重，有的時(shí)候甚至占到整體結(jié)構(gòu)物質(zhì)量的35%左右。</span> </p> <p> <span style="font-size:14px;">二，抗震性能不錯(cuò)。泡沫混凝土的彈性模量較低，具有良好的擴(kuò)散沖擊負(fù)荷的功能，同時(shí)泡沫混凝土能夠消耗地震波帶來的沖擊能量。</span> </p> <p> <span style="font-size:14px;">三，膈音性能較強(qiáng)。因?yàn)榇嬖谥忾]孔，所以泡沫混凝土的隔音效果很好。在高速公路兩邊安裝的隔音板就是很明顯的例子。</span> </p> <p> <span style="font-size:14px;">四，耐火性能良好。泡沫混凝土本身就是一種無機(jī)材料，而無機(jī)材料都是不可自燃的，因此它是一種良好的耐火材料。</span> </p> <p> <span style="font-size:14px;">五，隔熱保溫性能較高。泡沫混凝土整體性能良好，不僅節(jié)能效益高，而且耐老化，保溫性能也很強(qiáng)。同時(shí)，在保溫效果得以保證的前提下，使用泡沫混凝土還能新增建筑面積，提高房地產(chǎn)開發(fā)商的經(jīng)濟(jì)效益。</span> 昆明發(fā)泡混凝土公司哪家好？</p><div

style="font-size:14px;">在普通混凝土的制備中，混凝土的強(qiáng)度隨成型水灰比的減小而增大，但在泡沫混凝土試驗(yàn)中發(fā)現(xiàn)的情況卻不盡相同。</span> </p> <p> <span style="font-size:14px;">1) 在漿體的流動(dòng)性主要依靠外加劑的用量來控制時(shí)(即漿體已經(jīng)具備良好的流動(dòng)性)，隨著水灰比的減小，強(qiáng)度增大；反之，減小。分析原因:隨著水灰比的減小，混凝土中的游離水量減少，泡沫混凝土的吸水率降低，有效增加了混凝土強(qiáng)度；但當(dāng)水灰比繼續(xù)降低時(shí)，由于水泥水化的需水量不足會(huì)吸收泡沫中的水分，使得泡沫破裂，從而引起封閉氣泡數(shù)量減少和混凝土均勻性下降，造成強(qiáng)度降低。</span> </p> <p> <span style="font-size:14px;">2)在漿體的流動(dòng)性主要依靠水的用量來控制時(shí)，隨著水灰比的增大，強(qiáng)度增大；反之，減小。</span> </p> <p> <span style="font-size:14px;">分析原因：較高的成型水灰比，保證了漿料的良好流動(dòng)性，能確保將泡沫均勻引入到水泥漿料中并均勻分布，從而實(shí)現(xiàn)強(qiáng)度的增長。相反，水灰比的降低，漿體材料流動(dòng)性不足，將引起氣泡分布不均，從而降低混凝土的強(qiáng)度。</span>
