Problems solved by technology

The permeable brick prepared by this method does not fully consider the combination of spherical ceramsite with different particle sizes, which is likely to cause the most compact accumulation of large and small particle size ceramsite, which seriously affects the water permeability effect (water permeability coefficient (15°C) is 0.05cm / s)

Embodiment 1

[0026] A method for manufacturing ceramsite permeable bricks by using polishing waste residue, the steps comprising:

[0027] a) Prepare polishing waste slag-based ceramsite: according to the mass percentage, weigh 30% of polishing waste slag, 20% of metal slag, 15% of clay, 5% of manganese ore powder, and 30% of limestone; mix and sieve the weighed raw materials Forming into balls, drying, and finally firing in a rotary kiln at 1000°C to obtain ceramsite;

[0028] The use of polishing waste slag to make ceramsite is because the polishing waste slag contains a relatively high amount of fine SiC, which can be decomposed to form a closed pore structure during high-temperature firing. The connected closed pores enable sound waves to propagate in the pores and generate energy attenuation. The sound absorption effect is obtained; and the ceramsite made has a special three-dimensional interconnected pore structure. When the rainwater passes through, the suspended solids, colloids, m...

Embodiment 3

[0052] A method for manufacturing ceramsite permeable bricks by using polishing waste slag, the steps comprising:

[0053] a) Prepare polishing waste slag-based ceramsite: according to the mass percentage, weigh 49% of polishing waste slag, 18% of metal slag, 13% of clay, 0% of manganese ore powder, and 20% of slaked lime; mix and sieve the weighed raw materials Forming into balls, drying, and finally firing in a rotary kiln at 1050°C to obtain ceramsite;

[0054] The use of polishing waste slag to make ceramsite is because the polishing waste slag contains a relatively high amount of fine SiC, which can be decomposed to form a closed pore structure during high-temperature firing. The connected closed pores enable sound waves to propagate in the pores and generate energy attenuation. The sound absorption effect is obtained; and the ceramsite made has a special three-dimensional interconnected pore structure.

Abstract

The invention provides a method for making a ceramsite water permeable brick by utilizing polishing waste residue. The method comprises the following steps: ceramsite preparation and screening, bottom-layer material preparation, middle-layer material preparation, surface-layer material preparation, material distribution formation, and maintenance and demoulding, so that the ceramsite water permeable brick is made. According to the invention, the ceramsite water permeable brick made by utilizing ceramsite prepared with polishing waste residue has high strength and water permeability, has a good sound absorption effect, and plays a role of noise reduction, has good effects of adsorbing heavy metal ions and filtering, and facilitates environmental protection; an unique three-layer water permeable structure facilitates permeation of water, improves the water permeability, realizes recycling of resources at the same time and greatly reduces the environment stress; furthermore, the making method is simple.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for manufacturing ceramsite permeable bricks by using polishing waste slag. Background technique [0002] Polishing waste is mainly produced during the grinding and polishing of ceramic tiles, and its components are mainly silicon carbide, magnesium oxide, magnesium chloride and brick chips in the polishing grinding head. According to statistics, the annual output of polished brick polishing waste in my country is as high as 7 to 8 million tons, and it shows an increasing trend year by year. Ceramic tiles made of polishing waste as raw materials are prone to foaming and deformation problems during firing, which limits their recycling to produce wall and floor tiles. Most ceramic factories use landfills to deal with polishing waste. Landfilling of polishing waste not only consumes manpower and material resources, but also pollutes groundwater quality. Some ce...
