水泥是工程建设中“三大主材”之一,使用范围广、消耗量大,在国民经济建设中占有重要位置。但是,做为工程主体的混凝土,其生产工艺落后,单方水泥用量高、浪费大、质量差,投入多产出少,仍是施工中的主要薄弱环节,必须引起足够的重视。 Cement is one of the “three main materials” in engineering construction. It has a wide range of uses and a large amount of consumption, and occupies an important position in the national economic construction. However, as the main part of the project, the concrete has a backward production process, high unilateral cement consumption, large waste, poor quality, and low input and output. It is still the main weakness in construction and must be given sufficient attention.
