Production method for producing autoclaved sand-lime bricks with copper tailings
The invention relates to a production method for producing autoclaved sand-lime bricks with copper tailings. The method is characterized in that the sand-lime bricks comprise, by mass, 35-45% of the copper tailings sand, 8-12% of calcium carbide slag, 15-20% of stone chips, and 30-35% of fine sand. An effective calcium oxide content of the calcium carbide slag is no lower than 65%. A silicon dioxide content of the copper tailings sand is no lower than 35%. The water content of the stone chips is no higher than 3%. The water content of the fine sand is no higher than 7%. According to the invention, the autoclaved sand-lime bricks are produced with the copper tailings with high water content, such that the copper tailings are fully utilized, and the produced autoclaved sand-lime bricks have high compressive strength and high flexural strength. With the method, enterprise cost is reduced, the environment is effectively protected, safety risk is eliminated, and an effective promotion is provided for the development of the metallurgical industry.
