混凝土配合比不当或砂、石子、水泥材料加水量计量不准，造成砂浆少、石子多； 混凝土搅拌时间不够，未拌合均匀，和易性差，振捣不密实。或者混凝土浇筑高度过高，造成混凝土离析。
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.
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.
结构物外露的表面应平整，无蜂窝、麻面、露筋及空洞。
The exposed surface of the structure shall be even, and shall be free from honeycombs, pitting surface, exposed reinforcing bars and cavities.
