style="text-indent:25px">泡沫混凝土除了干密度、導(dǎo)熱系數(shù)、抗壓強(qiáng)度這三個(gè)主要參數(shù)外，還有吸水率、干燥收縮值這幾個(gè)參數(shù)占有一定影響。一、吸水率：吸水率是衡量泡沫混凝土的耐久性及物理性的一項(xiàng)重要技術(shù)指標(biāo)。影響混凝土耐久性的各程破壞過程幾乎都與水有著密切的關(guān)系。1，泡沫混凝土吸水后可降低其抗凍性能，吸水越多，抗凍性越差;2，各種有害物質(zhì)均以水為載體。侵入泡沫混凝土的內(nèi)部，從內(nèi)部侵蝕混凝土，使之破壞;3，水進(jìn)入泡沫混凝土，久后蒸發(fā)，攜帶的溶解性鹽堿物質(zhì)，可使表面堿化粉裂并泛白霜，縮短其使用壽命;4，吸水后混凝土強(qiáng)度下降，保溫性降低。泡沫混凝土內(nèi)部氣孔多，雖說氣孔基本上是封閉型的，但也存在一定吸水率，云南輕質(zhì)混凝土公司，要求泡沫混凝土完全不吸水是不現(xiàn)實(shí)的，也沒有必要。越出色泡沫混凝土氣孔封閉率越高，吸水率越低，云南輕質(zhì)混凝土公司。二、干燥收縮值由于泡沫混凝土的密度低，內(nèi)部孔隙多，云南輕質(zhì)混凝土公司，更容易出現(xiàn)干燥收縮。如果現(xiàn)澆泡沫混凝土制品裂縫多，更易吸水。昆明輕質(zhì)發(fā)泡混凝土廠家哪家好？云南輕質(zhì)混凝土公司</p><div

style="text-indent:25px">云南發(fā)泡混凝土的應(yīng)用范圍：1.用作擋土墻。主要用作港口的巖墻。云南泡沫混凝土水泥地暖墊層在岸墻后用作輕質(zhì)回填材料可降低垂直截荷，也減少了對(duì)岸墻的側(cè)向載荷。這是因?yàn)榕菽炷潦且环N粘結(jié)性能良好的剛性體，它并不沿周邊對(duì)岸墻施加側(cè)向壓力，沉降降低了，維修費(fèi)用隨之減少，從而節(jié)省很多開支。云南泡沫混凝土也可用來增進(jìn)路堤邊坡的穩(wěn)定性，用它取代邊坡的部分土壤，由于減輕了質(zhì)量，從而就降低了影響邊坡穩(wěn)定性的作用力。2.管線回填。地下廢棄的油柜、管線、污水管及其他空穴容易導(dǎo)致火災(zāi)或塌方，采用云南泡沫混凝土回填可解決這些后患，費(fèi)用也少。3.修建運(yùn)動(dòng)場(chǎng)和田徑跑道。使用排水能力強(qiáng)的可滲性云南泡沫混凝土作為輕質(zhì)基礎(chǔ)，上面覆以礫石或人造草皮，作為運(yùn)動(dòng)場(chǎng)用。4.作夾芯構(gòu)件。在預(yù)制鋼筋混凝土構(gòu)件中可采用云南泡沫混凝土作為內(nèi)芯，使其具有輕質(zhì)隔熱的良好性能。昆明泡沫現(xiàn)澆混凝土施工工程昆明泡沫輕質(zhì)混凝土公司哪家好？</p><div

style="text-indent:25px">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)。昆明輕質(zhì)混凝土哪家廠家好？云南輕質(zhì)混凝土公司</p><p
