混凝土麻面是指混凝土浇筑后,由于空气排除不干净,或是由于混凝土浆液渗漏造成的混凝土表面有凹陷的小坑和表面不光滑,不平整的现象。 结构构件表面上呈现无数的小凹点,而无钢筋暴露的现象。它是由于模板表面粗糙、未清理干净、湿润不足、漏浆、振捣不实、气泡未排出以及养护不好所致。 混凝土构件表面上出现麻面现象,往往伴随着蜂窝现象。

摘要:混凝土通常出现严重的麻面、缝隙、蜂窝、孔洞、裂缝等通病。
Abstract: : the concrete usually appear serious pits, gap, cellular, hole, crack problems, etc.
如果再加上振捣不合理,大气泡不能完全排出,肯定会给硬化混凝土结构表面造成蜂窝麻面。
If the unreasonable vibration, large bubbles can not be completely discharged, would certainly have resulted in hardening the surface of concrete structure surface cellular Ma.
桥面铺装防水混凝土表面不得有麻面、蜂窝和裂纹,施工缝处不得有裂缝。
No honeycombs, pitting surface and cracks may exist on the surface of the waterproofing concrete along the bridge deck pavement, there shall be no cracks at the construction joints.
