Chinese patent CN103073329A discloses a method of manufacturing colored square permeable bricks with coal gangue as the main raw material. The method adopts the two-step sintering method of calcining coal gangue first and then adding auxiliary raw materials to prepare permeable bricks. This method consumes a lot of energy, and It is difficult to scale up production
[0005] At present, no relevant patents have been found on the use of blast furnace water-quenched slag and coal gangue to prepare permeable bricks

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a water seepage brick, in particular to a low-energy sintered water seepage brick with industrial waste residue as the main raw material and a manufacturing method thereof. Background technique [0002] Blast furnace water-quenched slag is a kind of loose and porous particles formed when the molten slag is water-quenched and quenched during blast furnace smelting. Each ton of pig iron will produce 0.25 to 1.2 tons of blast furnace water-quenched slag. At present, the blast furnace water-quenched slag accumulated in my country's slag yards has exceeded 100 million tons. Preparation of cement, concrete, and foam glass are the main methods for utilizing blast furnace water-quenched slag, but generally speaking, the comprehensive utilization rate of blast furnace water-quenched slag is insufficient and the added value of the product is low. [0003] The use of...
