当前,我国各地使用加气混凝土做外墙日益增多,作为试验建筑当然可以。但是,一些城市不止一幢的大量推广,似乎有为时尚早之感。其原因之一就是这种墙体的耐久性,尤其是面层在若干年后是否会剥落的问题。目前许多施工单位对于加气混凝土面层抹灰的问题做了许多工作,以增强粘结力和减少面层裂缝为主,这是问题的一个方面;另外一个更重要的问题就是如何科学的估价 At present, the use of aerated concrete as an external wall in various parts of our country is increasing. It is of course possible to use it as a test structure. However, it seems that it is too early for some cities to promote more than one building. One of the reasons for this is the durability of this type of wall, especially if the surface layer will peel off after several years. At present, many construction companies do a lot of work on the problem of plastering the surface of aerated concrete to increase adhesion and reduce surface cracks. This is an aspect of the problem; another, more important issue is how to scientifically estimate
