1982年我国水泥总产量超过9000万吨,混凝土总产量估计可达6亿吨。但是,我国的混凝土工业可以说至今还未建立起来。这样说的根据是:(1)标志近代混凝土工业发展的主要方向、在发达国家已成为混凝土工业骨干的商品混凝土,在我国几乎等于零;(2)已建立的中心搅拌站以至预制构件厂,绝大多数是属于某单位或某工程自给性质的;(3)现有的水泥制品厂和混凝土制品厂的年产量还很小,不超过150万立方米,加上农房构件也不过350万立方米左右,水泥转化率(即水泥产量中用来制作混凝土制品的百分率)还不到1.2%;(4)缺少技术开发中心等类型的全国性统筹规划、研究开发、检测监督、情报培训的机构,而这类由国家授权的中心,对于新建工业的发展是十分重要的。现就上述有关问题说明如下:
In 1982, China’s total cement output exceeded 90 million tons, and the total concrete production is estimated to reach 600 million tons. However, China’s concrete industry can be said to have not yet been established. The basis for this is: (1) marking the main direction of development of the modern concrete industry, and the commodity concrete that has become the backbone of the concrete industry in the developed countries, which is almost equal to zero in our country; (2) the established central mixing plant and even the prefabricated component plant. Most of them belong to the self-sufficiency nature of a certain unit or project; (3) The annual output of existing cement products and concrete products plants is still very small, not exceeding 1.5 million cubic meters, and only 3.5 million cubic meters of agricultural housing components are added. About meters, the cement conversion rate (ie, the percentage of cement production used to make concrete products) is less than 1.2%; (4) The lack of technical development centers and other types of national overall planning, research and development, testing and supervision, intelligence training organizations This kind of state-authorized center is very important for the development of new industries. The above related issues are described as follows:
