粉煤灰加气混凝土砌块(以下简称“加气块”)是一种新型建筑材料。由于它具有容重轻、热工性能好等的优点,愈来愈广泛地用以砌筑各种建筑体系的墙体。但是有人议论在这种墙体上抹灰容易裂缝和空壳,关于裂缝和空壳成因的说法也较多。为了解决粘结力差的问题,又有各种各样的基面处理方法,众说纷纭。为此,自1982年以来,我们进行了加气块墙体抹灰施工工艺的试验 Fly ash aerated concrete block (hereinafter referred to as “aerated block”) is a new building material. Due to its advantages of light weight and good thermal performance, it is increasingly used to masonry various types of building systems. However, there are people who talk about the easy cracking and empty shell plastering on this type of wall. There are also many arguments about the causes of cracks and empty shells. In order to solve the problem of poor cohesion, there are a variety of ground handling methods, and there are many opinions. For this reason, since 1982, we have conducted tests on the aerated block wall plastering process.
