style="font-size:14px;">我國(guó)泡沫混凝土發(fā)展并不晚，僅次于歐洲。1950年，前蘇聯(lián)**就開(kāi)始向中國(guó)推廣泡沫混凝土技術(shù)。1952年，中國(guó)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(kāi)始了中國(guó)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(lái)，泡沫混凝土在我國(guó)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(guó)泡沫混凝土年生產(chǎn)總量已突破600萬(wàn)m3，其中，現(xiàn)澆類約占生產(chǎn)總量80%以上，其他約20%。</span> </p><p style="text-indent:25px"><span style="font-size:14px;">泡沫混凝土具有極強(qiáng)的抗沖擊性能。用大錘能把普通混凝土砸破，但難以砸破泡沫混凝土。利用它的這種吸能性，國(guó)外已經(jīng)研發(fā)和應(yīng)用了一批高附加值產(chǎn)品，如飛機(jī)場(chǎng)安全防護(hù)泡沫塊、賽車場(chǎng)安全防護(hù)泡沫塊、公路事故易發(fā)地帶安全防護(hù)泡沫塊等。當(dāng)飛機(jī)、汽車因失控沖出跑道或道路時(shí)，進(jìn)入發(fā)泡塊防護(hù)帶，由于泡沫塊的沖擊力吸收性能，使其停滯并保護(hù)飛機(jī)或車輛無(wú)損。泡沫混凝土對(duì)子dan沖擊波及沖擊波具有良好的吸收作用，可極大可能降低射擊及的破壞力。在抗方面，具有開(kāi)發(fā)意義的產(chǎn)品有***、民用兩類。</span>昆明輕質(zhì)發(fā)泡混凝土哪家好？</p><div

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)?；瘜W(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(guò)調(diào)節(jié)發(fā)泡倍數(shù)以及改變水灰比來(lái)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>
