第十一冶炼厂利用赤泥生产硅酸盐水泥,在1964年《有色金属》第4期已做过报道。经过两年多的科学试验和生产实践,职工同志们在努力提高赤泥配比和改进水泥质量方面,又取得了新的成就,成功地生产出“低硅高铁”优质水泥。主要的成就可归纳为如下几点:1.赤泥的配料比提高至50～60%,比生产一般硅酸盐水泥提高一倍。因而可以缩小水泥厂规模,节 The eleventh smelter uses red mud to produce Portland cement, which was reported in the fourth edition of Nonferrous Metals, 1964. After more than two years of scientific experiments and production practices, the workers and staff have made new achievements in efforts to improve the red mud ratio and improve the cement quality, and succeeded in producing “low-silicon high-speed rail” high-quality cement. The main achievements can be summarized as follows: 1 red mud ingredients ratio increased to 50 ~ 60%, double the production of ordinary Portland cement. Which can reduce the size of cement plant, section
