据中国加气混凝土工业协会透露,1981年我国加气混凝土总产量约为85万立米,比1980年增长30％。产品的平均抗压强度是27.47公斤/厘米~2,比1980年提高1.5％。年产8万立米以上的企业其利润总额为452.9万元,比1980年增长32.5％。截止去年底,已经投产的企业为43个,我国加气混凝土工业已经初步形成了一个大、中、小结合的产业结构。当前存在的主要问题是:①管理水平不高;②基本建设不配套;③产品应用还没有完全打开局面。今年,协会准备重点抓好上述三个问题。
According to the China Aerated Concrete Industry Association, the total output of aerated concrete in China in 1981 was about 850,000 cubic meters, a 30% increase over 1980. The average compressive strength of the product was 27.47 kg/cm 2 , which was 1.5% higher than in 1980. Enterprises with an annual output of 80,000 cubic meters or more have a total profit of 4.529 million yuan, an increase of 32.5% over 1980. By the end of last year, 43 enterprises had already been put into operation. China’s aerated concrete industry has initially formed a large, medium, and small industrial structure. The main problems that currently exist are: 1) the level of management is not high; 2) the basic construction is not supporting; 3) the application of products has not completely opened up the situation. This year, the association is ready to focus on the above three issues.
