在混凝土的施工过程中常常会出现如麻面、漏筋、蜂窝、孔洞等通病,那么是怎么产生这些问题的呢?如何去防治与修补呢?下面我就这几个问题做一下分析:1.麻面所谓麻面是指混凝土构件表面局部缺浆粗糙,出现无数的小凹坑,但无漏筋现象。它产生的原因主要有:(1)木模板在浇筑混凝土前没有充分湿润或湿润不够;(2)模板的重复使用,表面清理不干净,粘
In the concrete construction process, common problems such as pockmarks, leaky ribs, honeycombs, and holes are often present. How do these problems arise? How do we prevent and repair them? Now I will analyze these issues: 1 Mamian The so-called pockmark refers to the partial lack of rough surface on the surface of the concrete component, and there are countless small pits, but no leakage phenomenon. The main reasons for this are: (1) The wood formwork is not sufficiently moist or wet enough before the concrete is poured; (2) The template is repeatedly used, the surface is not clean, and the surface is not clean.
