一、碳纖維布是什么加固材料

加固材(cai)料(liao)是(shi)對建(jian)筑物進行加固處理的材(cai)料(liao)，碳纖維(wei)布(bu)(bu)就是(shi)一種常用的加固材(cai)料(liao)，是(shi)利用專(zhuan)用結構(gou)膠將碳纖維(wei)布(bu)(bu)粘貼(tie)在混凝(ning)土(tu)表面，形成復合結構(gou)，碳纖維(wei)布(bu)(bu)通過與混凝(ning)土(tu)之間(jian)協同(tong)工(gong)作，對構(gou)件或(huo)結構(gou)起到加固及改善受力性(xing)能(neng)的作用，能(neng)有效改善結構(gou)狀(zhuang)態（減(jian)少變形、降低原有結構(gou)應力、減(jian)少裂(lie)縫(feng)）。

二、加固碳纖維布需要送檢嗎

需要。

加固(gu)碳纖(xian)維布(bu)不僅施(shi)工(gong)(gong)(gong)前(qian)需要(yao)(yao)(yao)送檢(jian)(jian)，加固(gu)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)完工(gong)(gong)(gong)后(hou)也需要(yao)(yao)(yao)對碳纖(xian)維布(bu)及工(gong)(gong)(gong)程(cheng)(cheng)(cheng)的(de)質量進行(xing)復檢(jian)(jian)，這是《工(gong)(gong)(gong)程(cheng)(cheng)(cheng)結構(gou)加固(gu)材料安全性鑒定(ding)技術規(gui)范》工(gong)(gong)(gong)程(cheng)(cheng)(cheng)規(gui)范要(yao)(yao)(yao)求的(de)規(gui)定(ding)：在工(gong)(gong)(gong)程(cheng)(cheng)(cheng)正式(shi)施(shi)工(gong)(gong)(gong)前(qian)和(he)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)完工(gong)(gong)(gong)后(hou)，都(dou)需要(yao)(yao)(yao)對工(gong)(gong)(gong)程(cheng)(cheng)(cheng)所(suo)用(yong)的(de)加固(gu)材料進行(xing)一個安全性的(de)檢(jian)(jian)測。

由于碳纖維(wei)布用于加(jia)固(gu)處理，如(ru)果使用了不合格的(de)碳纖維(wei)布，會對建(jian)筑結構造成危害，因此需要選擇正規(gui)廠家生(sheng)產的(de)加(jia)固(gu)碳纖維(wei)布，并(bing)保證其各項指(zhi)標數據(ju)能通(tong)過檢查。

三、加固碳纖維布檢測項目有哪些

加固碳纖維(wei)布送檢(jian)需要檢(jian)測的項目有很(hen)多：

1、施工(gong)前，需(xu)要(yao)檢測(ce)加固碳纖(xian)維(wei)布的材料力學性能(neng)，包(bao)括其抗拉(la)強度、彈性模量和伸長率等。

2、施工完成后，復檢主要是通過錘擊法來檢測碳纖維布的粘貼質量，通過對每(mei)一寸的碳纖(xian)(xian)維布進行(xing)錘(chui)擊，檢測(ce)碳纖(xian)(xian)維布與混(hun)凝土(tu)之間是否存在空(kong)鼓(gu)(gu)情況，如發現(xian)空(kong)鼓(gu)(gu)，則說明碳纖(xian)(xian)維布與混(hun)凝土(tu)沒(mei)有(you)完全貼合(he)，沒(mei)用達到(dao)共同受力的目的，如空(kong)鼓(gu)(gu)面積低(di)于施(shi)工總(zong)面積的95%，則說明此次加固工程是不合(he)格的，需(xu)要對工程進行(xing)返(fan)工。
