干拌復(fu)合輕(qing)集(ji)(ji)料混凝土墊(dian)層簡稱：復(fu)合輕(qing)集(ji)(ji)料墊(dian)層調(diao)換(huan)。濟(ji)南陶粒(li)混凝(ning)土墊層(ceng)做法：

一、都會已限定應用粘土陶粒(li)，頁(ye)巖(yan)陶粒(li)，實際上無陶粒(li)供給，經(jing)研討(tao)，實驗，開辟一種干拌復合輕(qing)(qing)集(ji)料混凝(ning)土墊(dian)(dian)層（簡稱(cheng)：復合輕(qing)(qing)集(ji)料墊(dian)(dian)層）取代(dai)陶粒(li)混凝(ning)土，此干拌料現(xian)場加水攪(jiao)拌便可施工。

二、08BJ1-1《工程做法(fa)》等圖(tu)會(hui)合各樓面墊層中陶粒(li)混凝(ning)土密度按1800kg/m3盤算的(de)(de)，樓面墊層換用(yong)B型復合輕集料(liao)墊層后，密度≤840kg/m3，各樓面做法(fa)的(de)(de)靜荷(he)載已作改動(dong)。

三、A型干拌(ban)復合輕(qing)集料混凝(ning)土墊層(ceng)

1、A型干(gan)(gan)拌(ban)(ban)復合輕(qing)集料(liao)(liao)混凝(ning)土墊(dian)(dian)(dian)層(ceng)產物先容　A型干(gan)(gan)拌(ban)(ban)復合輕(qing)集料(liao)(liao)混凝(ning)土墊(dian)(dian)(dian)層(ceng)粉料(liao)(liao)是(shi)由(you)水泥、粉煤(mei)灰和(he)外加劑經工(gong)場制(zhi)成(cheng)的(de)平均干(gan)(gan)拌(ban)(ban)粉料(liao)(liao)，復合輕(qing)集料(liao)(liao)是(shi)由(you)破裂的(de)廢(fei)聚氨酯(zhi)顆粒(li)與有機膠(jiao)凝(ning)資料(liao)(liao)復合而成(cheng)，在(zai)施工(gong)現場骨料(liao)(liao)與預拌(ban)(ban)墊(dian)(dian)(dian)層(ceng)粉料(liao)(liao)和(he)水混雜攪(jiao)拌(ban)(ban)制(zhi)成(cheng)復合輕(qing)集料(liao)(liao)墊(dian)(dian)(dian)層(ceng)。　A型干(gan)(gan)拌(ban)(ban)復合輕(qing)集料(liao)(liao)混凝(ning)土墊(dian)(dian)(dian)層(ceng)具備質輕(qing)、輕(qing)工(gong)機能好、定量包(bao)裝(zhuang)無需現場稱量、配制(zhi)工(gong)藝(yi)簡(jian)略(lve)等凸起長處(chu)。層(ceng)面能夠承重，能夠按(an)應(ying)用請求鋪設排水坡度(du)，大大便(bian)利計劃和(he)施工(gong)。

2、A型干拌(ban)復合(he)輕(qing)集(ji)料混(hun)凝土(tu)(tu)墊層(ceng)(ceng)(ceng)施工辦法：下(xia)層(ceng)(ceng)(ceng)處置：在鋪設A型干拌(ban)復合(he)輕(qing)集(ji)料混(hun)凝土(tu)(tu)墊層(ceng)(ceng)(ceng)以前(qian)將樓板下(xia)層(ceng)(ceng)(ceng)停止處置，把粘結(jie)在下(xia)層(ceng)(ceng)(ceng)上(shang)的松動混(hun)凝土(tu)(tu)、沙漿等用(yong)鏨子剔(ti)掉，用(yong)鋼絲刷(shua)(shua)刷(shua)(shua)掉水(shui)泥(ni)漿皮，而后用(yong)掃(sao)(sao)帚掃(sao)(sao)凈。找(zhao)標高彈程度控制線:依據墻(qiang)上(shang)的+1250px程度標高線，往(wang)下(xia)量測(ce)出墊層(ceng)(ceng)(ceng)標高，有條件時可彈在周(zhou)圍墻(qiang)上(shang)。

A型干拌復合(he)輕集料(liao)(liao)混凝土墊(dian)層(ceng)攪(jiao)拌：先將過量水參加(jia)攪(jiao)拌機中(zhong)，而(er)后參加(jia)一袋預拌墊(dian)層(ceng)粉料(liao)(liao)，攪(jiao)拌成平(ping)(ping)(ping)均料(liao)(liao)漿再參加(jia)一袋復合(he)輕集料(liao)(liao)，再繼承(cheng)攪(jiao)拌構成平(ping)(ping)(ping)均的(de)拌合(he)物，便可施工。A型干拌復合(he)輕集料(liao)(liao)混凝土墊(dian)層(ceng)鋪設、振島或(huo)滾(gun)壓：鋪已攪(jiao)拌好干拌復合(he)輕集料(liao)(liao)混凝土墊(dian)層(ceng)，用(yong)鐵鍬(qiao)將墊(dian)層(ceng)鋪在下層(ceng)上，以已做好的(de)找(zhao)平(ping)(ping)(ping)墩為標準將灰攤平(ping)(ping)(ping)，比找(zhao)平(ping)(ping)(ping)堆超過跨(kua)過3mm,而(er)后用(yong)平(ping)(ping)(ping)板振搗器(qi)振實(shi)找(zhao)平(ping)(ping)(ping)。如厚度較薄時(shi)，可隨鋪隨用(yong)鐵鍬(qiao)和特制木點頭拍壓密(mi)實(shi)，并隨即用(yong)大杠找(zhao)平(ping)(ping)(ping)，用(yong)木抹子(zi)搓平(ping)(ping)(ping)或(huo)用(yong)鐵滔滔壓密(mi)實(shi)，全體操縱進程(cheng)要在3h內實(shi)現。
