(砂子)。</span> </p> <p> <span style="font-size:14px;">第1種情況:單獨采用水泥時相對簡單，所用水泥的強度等級越高、用量越多，制備的泡沫混凝土強度也就越大。所以，當(dāng)希望制備較**度的泡沫混凝土?xí)r，需要選擇**度等級的水泥。</span> </p> <p> <span

style="font-size:14px;">泡沫混凝土在如今的建筑行業(yè)上使用的比較多，因為它具有保暖、不燃的特點而被廣大客戶所青睞，那么用泡沫混凝土哪里做地暖有什么比較大的優(yōu)勢么?下面就由永欣建材為大家進行以下講解。</span> </p> <p> <span style="font-size:14px;">1、散熱均勻，舒適：</span> </p> <p> <span style="font-size:14px;">地暖系統(tǒng)的供暖原理為輻射傳熱，與空調(diào)、暖氣等通過強制對流循環(huán)熱風(fēng)供暖相比，空氣中灰塵流動要小的多，減少了空氣中有害病菌的蔓延，室內(nèi)環(huán)境更加衛(wèi)生清潔，地暖系統(tǒng)也創(chuàng)造性的運用了人體溫感特點，來自腳下的關(guān)懷讓您倍感舒適，讓您的家庭充滿溫暖。</span> </p> <p> <span style="font-size:14px;">2、清潔健康：</span> </p> <p> <span style="font-size:14px;">地暖系統(tǒng)可有效促進足部血液循環(huán)，從而改善全身血液循環(huán)，促進新陳代謝，對心血管疾病有控制作用;對老年人和兒童尤為適用，對于關(guān)節(jié)炎、老寒腿的病人更有防治功效。并在一定程度上提高自身免疫能力。</span> </p> <p> <span style="font-size:14px;">3、環(huán)保節(jié)能：</span> </p> <p> <span style="font-size:14px;">地暖系統(tǒng)采暖與傳統(tǒng)的對流供暖方式相比較節(jié)能幅度約為30%，地暖在傳送過程中熱量損失較小并且熱量集中在人體受益的高度內(nèi)，即使室內(nèi)設(shè)定溫度比對流式采暖方式低2～5℃，也能使人們有同樣的溫暖感覺。地暖可充分節(jié)約能源，并且不會發(fā)出任何噪音，不會揚塵，是一個非常環(huán)保節(jié)能的產(chǎn)品。</span> </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重要技術(shù)指標。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)實的，也沒有必要。越質(zhì)量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> 昆明發(fā)泡混凝土廠家哪家好？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="font-size:14px;">從泡沫混凝土的制備原理分析，利用發(fā)泡劑引入大量氣孔賦予其普通混凝土所沒有的輕質(zhì)、隔音、保溫、高流動性等功能是泡沫混凝土制備的基礎(chǔ)；但從結(jié)構(gòu)和力學(xué)的角度看，同時也引起結(jié)構(gòu)致密性極大可能降低，從而降低了泡沫混凝土的強度。發(fā)泡劑對泡沫混凝土強度的影響主要體現(xiàn)在泡沫的尺寸、均勻性(尺寸均勻性和分布均勻性)、泡沫的穩(wěn)定性、發(fā)泡能力等。要求發(fā)泡劑的發(fā)泡能力強、密度低、單位攜水量小，泡沫牢固、細小、均勻分布，對混凝土的副作用小。</span>泡沫輕質(zhì)混凝土公司哪家好？昆明輕質(zhì)混凝土施工工程</p><p style="text-indent:25px">昆明發(fā)泡混凝土哪家廠家好？昆明輕質(zhì)混凝土施工工程</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，混凝土的強度隨成型水灰比的減小而增大，但在泡沫混凝土試驗中發(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，從而實現(xiàn)強度的增長。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度。</span> 昆明輕質(zhì)混凝土施工工程</p><p
