遵照伟大领袖毛主席关于“综合利用很重要,要注意”的教导,焦作市用煤矸石制作空心砌块已投入试生产。由于我们以阶级斗争为纲,坚持党的基本路线,大搞群众运动,抓革命,促生产,试生产取得了很大成绩。为了进一步稳定砌块标号,缩短养护时间,探讨合理的生产工艺和煤矸石制品的硬化机理,拟逐步开展一些试验研究工作,最近仅就煤矸石的煅烧温度对砌块胶结料强度的影响作了一些探索性试验。 In accordance with the guidance of the great leader, Chairman Mao, on the “Importance of comprehensive utilization, attention should be paid”, Jiaozuo City has made trial production of hollow block made from coal gangue. As we classify our class struggle, we adhere to the Party’s basic line, engage in mass movements, grasp the revolution, and promote production. Trial production has achieved great results. In order to further stabilize the numbering of blocks, shorten the curing time, explore reasonable production techniques and the hardening mechanism of coal gangue products, it is planned to gradually carry out some experimental research work. Recently, only the effect of the calcination temperature of coal gangue on the strength of block cement has been made. Some exploratory tests.
