近来我们国家在基本建设中遇到了建筑材料紧张的问题,其中水泥更是突出。因此,各方面已广泛地展开研究克服这一困难的措施,例如无熟料水泥的制造及现场挽混合材料均给水泥的紧张解决了了许多困难。我们国家在水泥的生产上由于装配式钢筋混凝土预制构件的推广,已肯定了向高标号水泥发展,但在一般建筑方而却很大范围内乃需要大量的中级标号及低级标号的水泥,如用水泥厂生产的高标号水泥来供应这一种用途,不仅不合经济原则,浪费了水泥的活性,并且也不为产量所允许;即使水泥厂制造了这种水泥,结果将减少了高标号水泥的生产。从增加产量及产品习说,目前己在积极发展各种无熟料水泥的制造;另一方 Recently, our country has encountered the problem of building materials in the basic construction, among which cement is even more prominent. Therefore, various aspects have been extensively studied to overcome this difficulty. For example, the manufacture of clinker-free cement and the mixing of materials on site have solved many difficulties for cement. In the production of cement in our country due to the promotion of fabricated reinforced concrete prefabricated components, it has been confirmed that the development of high-grade cement, but in the general construction side but a large range of cement requires a large number of intermediate grades and low grades of cement, such as The use of high-grade cement produced by a cement plant to supply this type of use is not only inconsistent with the economic principle, it wastes the activity of the cement, and it is not allowed by the output; even if the cement plant produces such cement, the result will be a reduction of high-grade cement. Production. From the perspective of increasing production and product habits, it is currently actively developing the manufacture of various cements without clinker;
