加(jia)(jia)氣(qi)(qi)混(hun)(hun)凝(ning)(ning)土(tu)(tu)(tu)用(yong)加(jia)(jia)氣(qi)(qi)鋁(lv)(lv)粉(fen)(fen)主要的(de)用(yong)途是在生(sheng)(sheng)(sheng)產(chan)(chan)過程中(zhong)(zhong)(zhong)(zhong)鋁(lv)(lv)粉(fen)(fen)和二氧化硅、生(sheng)(sheng)(sheng)石灰(hui)發(fa)生(sheng)(sheng)(sheng)化學反(fan)應(ying)(ying)放出氣(qi)(qi)體，使生(sheng)(sheng)(sheng)產(chan)(chan)出的(de)混(hun)(hun)凝(ning)(ning)土(tu)(tu)(tu)砌塊內部(bu)形成(cheng)多孔結(jie)構(gou)。在加(jia)(jia)氣(qi)(qi)混(hun)(hun)凝(ning)(ning)土(tu)(tu)(tu)砌塊生(sheng)(sheng)(sheng)產(chan)(chan)過程中(zhong)(zhong)(zhong)(zhong)配料的(de)工藝中(zhong)(zhong)(zhong)(zhong)，將加(jia)(jia)氣(qi)(qi)加(jia)(jia)入鋁(lv)(lv)粉(fen)(fen)漿攪(jiao)拌罐中(zhong)(zhong)(zhong)(zhong)，經充分攪(jiao)拌后放入到鋁(lv)(lv)粉(fen)(fen)漿計量秤(cheng)中(zhong)(zhong)(zhong)(zhong)，最后和生(sheng)(sheng)(sheng)石灰(hui)，石膏，粉(fen)(fen)煤灰(hui)等原材料一起放入澆注攪(jiao)拌機中(zhong)(zhong)(zhong)(zhong)，鋁(lv)(lv)粉(fen)(fen)膏中(zhong)(zhong)(zhong)(zhong)的(de)鋁(lv)(lv)粉(fen)(fen)在加(jia)(jia)氣(qi)(qi)混(hun)(hun)凝(ning)(ning)土(tu)(tu)(tu)料漿中(zhong)(zhong)(zhong)(zhong)能與堿性物(wu)質(zhi)反(fan)應(ying)(ying)放出氫(qing)氣(qi)(qi)，產(chan)(chan)生(sheng)(sheng)(sheng)氣(qi)(qi)泡，使加(jia)(jia)氣(qi)(qi)混(hun)(hun)凝(ning)(ning)土(tu)(tu)(tu)料漿膨脹形成(cheng)多孔結(jie)構(gou)。從而使生(sheng)(sheng)(sheng)產(chan)(chan)出的(de)加(jia)(jia)氣(qi)(qi)混(hun)(hun)凝(ning)(ning)土(tu)(tu)(tu)砌塊一般重量為(wei)500-700kg/m3，只(zhi)相當(dang)于粘土(tu)(tu)(tu)磚1/4-1/5，普(pu)通(tong)混(hun)(hun)凝(ning)(ning)土(tu)(tu)(tu)的(de)1/5，是混(hun)(hun)凝(ning)(ning)土(tu)(tu)(tu)中(zhong)(zhong)(zhong)(zhong)的(de)較輕的(de)一種。比普(pu)通(tong)磚混(hun)(hun)凝(ning)(ning)土(tu)(tu)(tu)結(jie)構(gou)建筑的(de)自重降低40%以上。

另外使(shi)用加氣還可以(yi)使(shi)加氣混凝(ning)土(tu)砌塊具有以(yi)下效(xiao)果。

1.隔音效果

因(yin)其具(ju)有特有的(de)多孔結(jie)構(gou)，內部結(jie)構(gou)像(xiang)面包一(yi)樣，均(jun)勻地分(fen)布著(zhu)大量的(de)封閉(bi)氣孔，因(yin)而具(ju)有一(yi)定的(de)吸聲能(neng)力。10mm厚墻體可達(da)到41分(fen)貝。

2.抗震能力強

加(jia)氣混凝(ning)土砌(qi)塊容量輕、整體(ti)性(xing)能(neng)好(hao)、地震(zhen)(zhen)是的慣性(xing)小(xiao)，所(suo)以具有(you)一(yi)定的抗(kang)震(zhen)(zhen)能(neng)力。

3.保溫效果

由于加氣混(hun)凝土(tu)砌塊內部具有大量的氣孔和微孔，因(yin)而有良(liang)好的保溫隔熱性能。導熱系數為(wei)0.11-0.16W/MK，是粘(zhan)土(tu)磚(zhuan)的1/4-1/5。通(tong)常20cm厚的加氣混(hun)凝土(tu)墻(qiang)的保溫隔熱效果，相當于49cm厚的普通(tong)實心粘(zhan)土(tu)磚(zhuan)墻(qiang)。

4.抗滲效果

因加氣(qi)混凝(ning)土(tu)砌塊由許多獨立(li)的小氣(qi)孔組成，吸水(shui)導濕緩慢(man)，同(tong)體積吸水(shui)至(zhi)飽和所需時間是粘土(tu)磚的5倍(bei)。用(yong)于衛生間時，墻面(mian)進行界面(mian)處理(li)后即可(ke)直接(jie)粘貼瓷磚。
