style="font-size:14px;">一、施工時(shí)間短，不影響現(xiàn)有交通。特別是在施工周期短，昆明輕質(zhì)混凝土廠、在用地昂貴的經(jīng)濟(jì)發(fā)達(dá)地區(qū)、在建筑物及人口相對(duì)密集的地區(qū)進(jìn)行道路加寬改造、增建公路或輕軌線路時(shí)，采用這種技術(shù)能蕞大限度地節(jié)省用地，降低工程整體造價(jià)，具有明顯的綜合經(jīng)濟(jì)效益及社會(huì)效益?；侣范蔚穆坊钪藿ㄍㄟ^(guò)滑坡地段的公路時(shí)，為了防止土塊的滑動(dòng)，傳統(tǒng)的方法常常需要花費(fèi)大量的費(fèi)用和時(shí)間；</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)?；炷亮⒎襟w強(qiáng)度不僅與養(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(rùn)滑劑，試驗(yàn)時(shí)摩阻力就大大減小，所測(cè)得的抗壓強(qiáng)度較低。工程中實(shí)際采用的是不加潤(rùn)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(cè)得的強(qiáng)度也不同，立方體尺寸愈小，摩阻力的影響愈大，測(cè)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(zhǎng)為150mm的立方體試件，在28天齡期，用標(biāo)準(zhǔn)試驗(yàn)方法測(cè)得的抗壓強(qiáng)度。</span></p><p style="text-indent:25px"><span 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(méi)有的輕質(zhì)、隔音、保溫、高流動(dòng)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(shí)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(qiáng)度。發(fā)泡劑對(duì)泡沫混凝土強(qiáng)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(qiáng)、密度低、單位攜水量小，泡沫牢固、細(xì)小、均勻分布，對(duì)混凝土的副作用小。</span>昆明泡沫混凝土哪家公司好？</p><div

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(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。</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(guò)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(shuō)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(méi)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> 輕質(zhì)混凝土廠家哪家好？昆明輕集料混凝土施工價(jià)格</p><p

<span style="font-size:14px;">第1種情況:單獨(dú)采用水泥時(shí)相對(duì)簡(jiǎn)單，所用水泥的強(qiáng)度等級(jí)越高、用量越多，制備的泡沫混凝土強(qiáng)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(jí)的水泥。</span> </p> <p> <span style="font-size:14px;">第2種情況:混合材料的引入會(huì)導(dǎo)致泡沫混凝土早期強(qiáng)度的明顯降低，而對(duì)后期強(qiáng)度影響不大。如果填入適當(dāng)?shù)膹?qiáng)度激發(fā)劑，則可有效減緩前期強(qiáng)度降低。</span> </p> <p> <br /> </p> <p> <br />
