我厂革命职工遵照毛主席关于“综合利用大有文章可做”的教导,利用株洲洗煤厂的“洗矸”,成功地生产了烧结砖、平瓦、无熟料水泥及其空心砌块等。为了进一步发展轻质、高强、多功能的新型墙体材料,我们很希望利用这种煤矸石烧成陶粒,作混凝土的轻骨料。但是,这种煤矸石能不能象页岩那样,烧出内部密布互不连通的小孔、表面有坚硬外壳的陶粒来呢?为了回答这一问题,我们在厂党支部 In accordance with Chairman Mao’s guidance on “Making full use of many articles to do”, our revolutionary workers have successfully produced sintered bricks, plain tiles, clinker-free cement, and hollow blocks using the “washing” of Zhuzhou Coal Washery. . In order to further develop lightweight, high-strength, multi-functional new wall materials, we very much hope to use this coal gangue to burn ceramsite and use it as lightweight aggregate for concrete. However, can this kind of coal gangue not be able to burn out the small holes that are not connected to each other and have a hard shell on the surface like shale? To answer this question, we are in the factory branch.
