当前我国大中小厂水泥产量约为92Mt,国外水泥产量折算成混凝土约为6～7倍。我国小水泥质量低,混凝土产量较小,如以5倍折算,可得400～500Mt混凝土,约合220Mm~3,数量是十分大的。由于未发展商品化和专业化,因此效率低、消耗大。如果我国再不发展混凝土工业,走专业化商品化社会化 At present, China’s large, medium and small mills have a cement production of about 92 Mt, and foreign cement production is converted to concrete about 6 to 7 times. China’s small cement is of low quality and its concrete output is relatively small. If it is converted by 5 times, it can obtain 400-500 Mt of concrete, about 220 Mm-3, and the quantity is very large. Because it has not developed commercialization and specialization, it is inefficient and costly. If China does not develop the concrete industry again, it will take the socialization of specialized commercialization.
