Abstract

The invention specifically relates to a water permeable brick prepared from sulfuric acid waste residue and a preparation method of the water permeable brick. The water permeable brick, meeting the standard of GB / T28993-2010, is prepared from the locally abundant sulfuric acid waste residue and a local clay sintering agent through the working procedures of sieving, mixing, forming, drying, sintering and the like. The particles of the sulfuric acid waste residue in the raw materials are in the range of 6 to 120 meshes, so that the working procedure of breaking is not needed, the water permeable brick can be directly used after sieving, the energy consumption is reduced, the production cost is reduced, and the sintered clinker is extremely suitable for producing the water permeable brick by adopting a particle stacking method, the waste residue is fully utilized, and the environmental pollution is reduced. The water permeable brick prepared from the sulfuric acid waste residue is high in strength, high in water permeable performance, antifreeze and skid-resistant, and has high ecological environmental protection performance. The water permeable brick can be widely applied to the buildings such as plazas, urban roads, residential districts and parking lots. The construction of sponge cities is proposed by our country at present, and a large quantity of water permeable bricks are needed, so that the market prospect is wide.

Description

technical field [0001] The invention belongs to a permeable brick and a preparation method thereof, in particular to a permeable brick prepared by using sulfuric acid waste residue and a preparation method thereof. Background technique [0002] Permeable brick is a new century environmental protection building material product that was born to solve urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance. This product has the characteristics of maintaining the water permeability and moisture retention of the ground, non-slip, high strength, cold resistance, weather resistance, noise reduction, and sound absorption. It uses slag waste and waste ceramics as raw materials and is molded twice, which is a green and environmentally friendly product. [0003] At present, there are two methods of producing sintered permeable bricks at home and abroad: one is the method of adding pore-forming agents, which uses carbon particle...
