style="font-size:14px;">泡沫混凝土是加氣混凝土中的一個特殊品種，它的孔結(jié)構(gòu)和材料性能都接近于加氣混凝土，它們二者的差別，主要在氣孔形狀和加氣手段之間的差別。</span> </p> <p> <span style="font-size:14px;">1、泡沫混凝土則是通過機(jī)械制泡的方法，先將發(fā)泡劑制成泡沫，然后再將泡沫加入水泥、菱鎂、集料中，形成泡沫漿體，再經(jīng)自然養(yǎng)護(hù)等養(yǎng)護(hù)而成。加氣混凝土氣孔一般是橢圓形的，而泡沫混凝土受毛細(xì)孔作用的影響，產(chǎn)生變形，形成多面體；加氣混凝土是采用化學(xué)發(fā)氣，通過化學(xué)反應(yīng)，由內(nèi)部產(chǎn)生氣體而形成氣孔。</span> </p> <p> <span style="font-size:14px;">2、泡沫混凝土是一種利廢、環(huán)保、節(jié)能、價格低、性能好的新型保溫隔熱材料，它和加氣混凝土相比，可自然養(yǎng)護(hù)硬化，一般不需蒸壓；設(shè)備投入少，制作方便；生產(chǎn)十分簡單，投資很??；加氣混凝土蒸壓需龐大的設(shè)備投資，生產(chǎn)投資大，耗電耗能大，不利于環(huán)保節(jié)能。</span> </p> <p> <span style="font-size:14px;">3、更重要的是泡沫混凝土不但能在廠內(nèi)生產(chǎn)成各種各樣的制品，而且還能現(xiàn)場施工，直接現(xiàn)澆成屋面、地面和墻體。除了用于生產(chǎn)砌塊和墻板，泡沫混凝土還可以生產(chǎn)保溫耐火材料、管道保溫外殼。</span> </p> <p> <span

</p> <p> <span style="font-size:14px;">（1）隔熱性傳導(dǎo)率在0.05-0.15Kcai/mh℃之間，是普通水泥制品的20-32倍，保溫隔熱性能非常出色。</span> </p> <p> <span style="font-size:14px;">（2）輕量性密度為250-1600kg/m3之間，是普通水泥密度的1/5-1/8，是輕量產(chǎn)品，可有限減輕建筑物的負(fù)荷。</span> </p> <p> <span style="font-size:14px;">（3）隔音性形成多孔性眾多**氣孔，吸音能力可達(dá)0.09-0.19％，是普通水泥的5倍，可較易解決公寓建造過程中的居住空間隔音問題。（4）整體性好泡沫混凝土與地面結(jié)構(gòu)層及采填充在材料上都是混凝土產(chǎn)品，整體性好，而苯板材料在長期使用中（如高溫后）易變形，影響結(jié)構(gòu)的整體性。</span> </p> <p> <span style="font-size:14px;">（5）施工性能自動化工設(shè)備根據(jù)需要訂參數(shù)，可對各項(xiàng)指標(biāo)進(jìn)行調(diào)整以滿足特定的要求，施工性能良好。</span> </p><p> <span style="font-size:14px;">水灰比的影響</span> </p> <p> <span 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) 在漿體的流動性主要依靠外加劑的用量來控制時(即漿體已經(jīng)具備良好的流動性)，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，由于水泥水化的需水量不足會吸收泡沫中的水分，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)在漿體的流動性主要依靠水的用量來控制時，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，漿體材料流動性不足，將引起氣泡分布不均，從而降低混凝土的強(qiáng)度。</span> 昆明泡沫輕質(zhì)混凝土哪家公司好？</p><div

style="font-size:14px;">泡沫混凝土是一種保溫、隔熱、輕質(zhì)、不燃的新型建筑材料，泡沫混凝土的使用范圍比較普遍，下面就由永欣建材為大家講解一下泡沫混凝土在礦井中的使用。</span> </p> <p> <span style="font-size:14px;">回填材料：</span> </p> <p> <span style="font-size:14px;">傳統(tǒng)水泥膠結(jié)混凝土充填材料中所用水泥一般為42.5普通硅酸鹽水泥，用量為150～300kg/m3，水灰比約1.2～1.3，28d混凝土抗壓強(qiáng)度5.0～10.0MPa,水泥在膠結(jié)充填成本中占30～60%。一般噸煤成本約增加40元/噸。降低水泥用量及成本，是尋找適用于礦山新型充填材料的有效途徑。泡沫混凝土具有輸送方便、流動性好、價格便宜，利用不同級配的尾礦礦粉和水泥進(jìn)行配比，可以保持一定的強(qiáng)度，完全可以作為一種新型的充填體在煤礦采空區(qū)回填中使用。</span> </p> <p> <span style="font-size:14px;">冒落空洞充填：</span> </p> <p> <span style="font-size:14px;">采掘工作面頂板冒頂后會形成一定范圍和高度的空洞，若不及時處理及充填，將會造成支護(hù)體無法發(fā)揮其支撐作用，可能造成更大范圍的頂板事故及經(jīng)濟(jì)損失，也可能造成瓦斯積聚。</span> 泡沫輕質(zhì)混凝土哪家好？昆明輕質(zhì)泡沫混凝土施工工藝</p><p style="text-indent:25px">輕質(zhì)泡沫混凝土哪家公司好？昆明泡沫混凝土廠家</p><p> <span style="font-size:14px;">泡沫混凝土除了干密度、導(dǎo)熱系數(shù)、抗壓強(qiáng)度這三個主要參數(shù)外，還有吸水率、干燥收縮值這幾個參數(shù)占有一定影響。</span> </p> <p> <span style="font-size:14px;">一、吸水率：</span> </p> <p> <span style="font-size:14px;">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。</span> </p> <p> <span style="font-size:14px;">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;</span> </p> <p> <span style="font-size:14px;">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;</span> </p> <p> <span style="font-size:14px;">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;</span> </p> <p> <span style="font-size:14px;">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，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。</span> </p> <p> <span style="font-size:14px;">二、干燥收縮值由于泡沫混凝土的密度低，內(nèi)部孔隙多，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。</span> 昆明泡沫混凝土廠家</p><p
