Concrete is made of cement, sand and gravel, and admixture, admixture and water according to certain proportion and bee asphaltmeasuring regarding mixproportion formed by hydration of artificial stone. Cement and water in condensate sclerotic process, formed cement block sand and gravel unbond together. Such aggregate Stones and sand and cement block such aggregate of the elastic skeleton bear external crystallization. Elastic skeleton make concrete with elastic deformation lubricious characteristic, and cement blocks no hardening gel make concrete with modelling the nature, it needs to be deformed in a long time gradually hardening. Concrete internal structure is more plex, its mechanical properties also is more plicated. Today, the concrete in the construction process will appear different degree, different forms of crack, and this is a fairly mon and mon phenomenon in mass concrete, and particularly in the construction. Has bee the mon plaint residential quality problem, but also long plagued construction enterprises of a problem. This paper mainly introduces the cracking reason and preventive measures. Keywords: castinsitu concrete crack causes and prevention measures. 去掉字母下的劃線(xiàn) 設(shè)置頁(yè)腳 ，拉丁數(shù)字開(kāi)始 現(xiàn)澆混凝土施工裂縫的成因及預(yù)防措施 2 目 錄 前言 ……………………………………………………………………… 混凝土裂縫簡(jiǎn)述 ……………………………………… …… ………… 裂縫產(chǎn)生的主 要原因 ……………………………………………………… … … 裂縫的分類(lèi) ……………………………………………………………………… 分析 ……………………………………… …… …… …… … …… 塑性裂縫 ……… ………………………………………… …………… ………… 溫度裂縫 ……………………………… …………… …………………………… 不均勻沉陷裂縫 ………………………………………………………………… 裂縫 預(yù)防措施 …………………………………………………………
