[0015] Select kiln-process phosphoric acid tailings with high porosity and good strength, with a particle size of 1-12mm. Among them, the particle size of the surface layer material is controlled at 1-5mm, and the particle size of the base layer material is controlled at 3-12mm. Add Huaxin CA-325 Portland cement, mix evenly, add water, plasticizer and adhesive, and stir evenly. The concrete was poured into a mold with a size of 200×100×60 and pressed into shape. It can be maintained for one month.

Abstract

The invention provides a manufacturing method of bricks with water permeability and water storage ability. Kiln phosphoric acid tailings which have a large number of pore structures and higher strength are adopted as main raw materials, and cement, binder and auxiliary materials are added to manufacture the environment-friendly bricks with water permeability and water storage ability and higher strength. The kiln phosphoric acid tailings have multiple pores and good water permeability and water storage performance, and the invention fully utilizes the above characteristics to manufacture bricks with good water permeability and water storage performance; the stored water can account for over 25% of the weight of the brick, and simultaneously the pollution of phosphoric acid tailings on the environment is reduced and the product additional value is improved.

Description

technical field [0001] The invention relates to a brick production method, in particular to a production method for producing permeable and water-storage bricks using kiln process phosphoric acid tailings as the main raw material. Background technique [0002] Permeable water storage brick is a kind of ecological brick with porous structure, high strength and good wear resistance, which can realize the functions of water permeability, water retention and decoration. With the requirements of environmental protection, it has been widely used in some cities in my country in recent years. It can be widely laid in squares, sidewalks, parking lots, residential areas, etc., and can replenish groundwater resources, adjust surface temperature and humidity, and eliminate "heat island" phenomenon. , The function of maintaining the ecological balance of the surface. [0003] At present, the permeable and water-storage bricks on the market mainly include casting molding and sintering mol...
