我厂广大革命职工遵照毛主席关于“备战、备荒、为人民”和有关综合利用的伟大教导,为适应地区战备工程和工业民用建筑大量用砖的需要,根据发电厂粉煤灰泛滥而煤渣又供不应求的状况,通过试验,于70年5月份开始,生产不用煤渣的无骨料全粉煤灰硅酸盐砌块(下称无渣砌块)。两年多来,已生产了无渣砌块十二万立方米,其中约有70％用于防空战备工程。 The revolutionary workers of our factory follow the great teachings of Chairman Mao on preparing for war, preparing for waste and for the people and comprehensive utilization. In order to adapt to the needs of the regional combat readiness project and industrial civil buildings for the use of large amounts of bricks, the coal slag has been flooded according to the power plant fly ash. The situation in short supply, through tests, began in May of the year 70, producing an aggregate-free, all-powdered ash silicate block without coal slag (hereinafter referred to as slag-free block). For more than two years, 120,000 cubic meters of slag-free blocks have been produced, of which about 70% are used for anti-air combat readiness projects.
