style="font-size:14px;">當(dāng)澆注體表面不平整、吸水性較大或有油污污染時(shí)，如果不對澆筑面進(jìn)行預(yù)處理，后期澆筑的泡沫混凝土水分就會(huì)被澆筑面吸收，泡沫混凝土內(nèi)部氣體快速排出，從而導(dǎo)致內(nèi)部水化熱反應(yīng)時(shí)缺少足夠的水分，形成一個(gè)一個(gè)的氣泡，泡沫混凝土初凝后，這些地方就容易形成空鼓。泡沫混凝土做大體積澆筑時(shí)經(jīng)常出現(xiàn)開裂現(xiàn)象，這是什么原因造成的呢？因?yàn)榕菽炷猎牧现饕獮樗啵趯?shí)際施工過程中發(fā)現(xiàn)，水泥在水化過程中會(huì)釋放大量水化熱，因該項(xiàng)目填筑體體積較大，泡沫混凝土自身導(dǎo)熱性能較差，所以熱量在澆筑體內(nèi)部形成積聚，但是泡沫混凝土表面的熱量可以快速揮發(fā)，這樣就形成了內(nèi)外溫差，從而導(dǎo)致泡沫混凝土表面產(chǎn)生裂紋。</span></p><p style="text-indent:25px"><span style="font-size:14px;">泡沫混凝土的立方體抗壓強(qiáng)度是衡量混凝土強(qiáng)度的主要指標(biāo)。混凝土立方體強(qiáng)度不*與養(yǎng)護(hù)時(shí)的溫度、濕度和齡期等因素有關(guān)，而且與試件的尺寸和試驗(yàn)方法也有密切關(guān)系。在一般情況下，試件的上下表面與試驗(yàn)機(jī)承壓板之間將產(chǎn)生阻止試件向外自由變形的摩阻力，它將像兩道套箍一樣將試件套住，延緩了裂縫的發(fā)展，從而提高了試件的抗壓強(qiáng)度。破壞時(shí)，試件中部剝落。如果在試件的上下表面涂上潤滑劑，試驗(yàn)時(shí)摩阻力就大大減小，所測得的抗壓強(qiáng)度較低。工程中實(shí)際采用的是不加潤滑劑的試驗(yàn)方法。試驗(yàn)還表明，立方體的尺寸不同，試驗(yàn)時(shí)測得的強(qiáng)度也不同，立方體尺寸愈小，摩阻力的影響愈大，測得的強(qiáng)度也愈高。新《規(guī)范》.規(guī)定，混凝土立方體強(qiáng)度，系指按標(biāo)準(zhǔn)方法制作、養(yǎng)護(hù)的邊長為150mm的立方體試件，在28天齡期，用標(biāo)準(zhǔn)試驗(yàn)方法測得的抗壓強(qiáng)度。</span>昆明混凝土公司哪家好？</p><div

style="font-size:14px;">泡沫混凝土室外吸音材料市場主要是高速公路及鐵路兩旁的吸聲屏障。我國未來大力發(fā)展鐵路公路，吸聲屏障至少有3000萬m3以上的需求。目前道路用吸聲屏障主要是碎木屑水泥板及泡沫玻璃板。前者吸聲系數(shù)很低，不能滿足高速鐵路的需要，且不美觀，后者價(jià)格太高。而泡沫混凝土吸聲性能好，可滿足任何道路吸聲要求，而價(jià)格卻很低，我們應(yīng)不失時(shí)機(jī)開發(fā)。室內(nèi)吸聲有吸聲吊頂及吸聲墻面。泡沫混凝土在墻面吸聲上有很大市場優(yōu)勢。它與巖礦棉等纖維吸聲板相比，沒有切割安裝時(shí)讓渾身刺癢的缺點(diǎn)，且強(qiáng)度好，價(jià)格也低。在地鐵墻面，本產(chǎn)品將大有市場，在大型商場、車站候車室、影劇院、會(huì)議廳等其他建筑墻面也有極大的市場。</span>

style="font-size:14px;">我國泡沫混凝土發(fā)展并不晚，*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>
