我们结合编制《加气混凝土应用技术规程》进行了一次调查,先后对重庆、武汉、上海和厦门等地所建的加气混凝土建筑和生产厂进行了参观。在南方地区能否应用加气混凝土?其隔热性能如何?造价能否过关?墙体开裂能否减少、避免?这些是不少同志关心的问题。现将此次南行见闻,择几个主要问题,发表一些个人的看法。 We conducted a survey in conjunction with the preparation of the “Technical Specification for the Application of Aerated Concrete” and visited the building of aerated concrete and production facilities in places such as Chongqing, Wuhan, Shanghai and Xiamen. Can the use of aerated concrete be applied in the south, how does its thermal insulation performance, whether the cost can pass, and whether the cracking of the wall can be reduced or avoided? These are the concerns of many comrades. We will now visit the South Bank, select a few major issues, and publish some personal opinions.
