现浇混凝土表面裂缝也是目前建筑工程中的质量通病之一。由于裂缝在一定程度上将影响结构的强度、刚度、抗渗性和耐久性,建筑工程施工中的混凝土裂缝,主要是在施工时由于混凝土内外温差和混凝土凝固收缩产生拉应力所致。现浇混凝土表面裂缝的主要形式,有表面裂缝和贯通裂缝两种。根据多年来对现浇混凝土表面产生的裂缝原因进行分析,从施工方面防治,并提出控制现浇混凝土表面裂缝发生的措施和表面裂缝的处理一些经验体会,供大家参考。
現澆混凝土錶麵裂縫也是目前建築工程中的質量通病之一。由于裂縫在一定程度上將影響結構的彊度、剛度、抗滲性和耐久性,建築工程施工中的混凝土裂縫,主要是在施工時由于混凝土內外溫差和混凝土凝固收縮產生拉應力所緻。現澆混凝土錶麵裂縫的主要形式,有錶麵裂縫和貫通裂縫兩種。根據多年來對現澆混凝土錶麵產生的裂縫原因進行分析,從施工方麵防治,併提齣控製現澆混凝土錶麵裂縫髮生的措施和錶麵裂縫的處理一些經驗體會,供大傢參攷。

surface cracks in cast-in-situ concrete and is one of the quality common fault in architectural engineering. Due to the cracks in a certain degree wil affect the structure of strength, stiffness, permeability resistance and durability, the construction of concrete cracks, mainly in the construction of concrete temperature difference between inside and outside and solidification shrinkage of concrete caused by tensile stress is produced. The main form of cast-in-situ concrete surface crack, there are two kinds of surface crack and through crack. According to the years of cast-in-situ concrete surface cracks causes were analyzed, and the prevention from the aspects of construction, and put forward the control measure of cast-in-situ concrete surface crack occurred and surface crack with some experiences, for your reference.
