为了适应上海地区大量新建住宅建筑,对轻质高强新型墙体材料的需要,我厂大搞技术改造,由煤渣砖生产逐步改为生产加气混凝土砌块。在筹建加气混凝土砌块生产车间的过程中,我们探索了下列几个问题:①目前,国内生产加气混凝土都要用水泥,并且必须是500号普通硅酸盐水泥,而水泥是当前国家建设中的重点物资。是否可以不用水泥生产加气混凝土(或用一些低标号水泥),这样可以节约大量水泥,用于更急需的地方。
In order to adapt to the large number of newly-built residential buildings in Shanghai and the need for lightweight, high-strength new wall materials, our plant has engaged in technological transformation and gradually changed from cinder block production to production of aerated concrete blocks. During the preparation of the aerated concrete block production workshop, we explored the following issues: 1 At present, the domestic production of aerated concrete must be cemented, and it must be No. 500 ordinary portland cement, and cement is the current country. The key materials in construction. Whether it is possible to produce aerated concrete without cement (or use some low-grade cement) can save a lot of cement for more urgently needed places.
