Problems solved by technology

[0003] Serpentine is a good steelmaking additive and an indispensable raw material for the production of compound fertilizers. During the mining of serpentine, a large amount of tailings are associated. In addition, with the acceleration of urban construction, urban construction waste has also become an environmental A major source of pollution, a large amount of tailings and construction waste have not been properly utilized
Therefore, in view of the current situation of insufficient utilization of serpentine tailings and construction waste and environmental pollution, how to increase the added value of serpentine tailings and construction waste and develop new uses for serpentine tailings is an arduous task at present.

Embodiment 1

[0026] This embodiment relates to a permeable brick prepared from serpentine tailings and construction waste, including a surface layer and a bottom layer.

[0027] The total weight of the surface layer raw materials is 200g, including 80g of serpentine tailings with a particle size of 10-20 mesh, 80g of construction waste with a particle size of 10-20 mesh, 4g of high-efficiency binder, and 36g of silicate binder.

[0028] The total weight of raw materials for the bottom layer is 2000g, including 800g of serpentine tailings with a particle size of 5-10 mesh, 800g of construction waste with a particle size of 5-10 mesh, 40g of high-efficiency binder, and 360g of silicate binder.

[0029] see figure 1 , the preparation method of the above-mentioned permeable brick comprises the following steps;

[0030] 1) The raw materials are crushed by jaw crusher, and the materials are weighed and graded;

[0031] 2) Put the surface layer material into the mold first, pave it on the botto...

Abstract

The invention discloses a permeable brick prepared from serpentine tailings and construction waste and a preparation method thereof. The present invention selects serpentine tailings and construction waste as raw materials, carries out crushing, screening, and grading, uses high-efficiency binders and solid waste particles to form moldings, and maintains finished products. The prepared non-sintering permeable bricks are better than the indicators specified in national standards. Requirements, not only can make full use of solid waste serpentine tailings and construction waste, but also greatly increase the added value of solid waste, realize the resource recycling of solid waste, reduce the site resources occupied by landfill, It has important economic, social and ecological significance.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of resources, and in particular relates to a permeable brick prepared by using serpentine tailings and construction waste. Background technique [0002] With the acceleration of the country's urbanization and the expansion of the city's area, the "heat island" and "rain island" effects have increased year by year. The original urban drainage system has been unable to meet the drainage requirements, and the drainage facilities lag behind the urban construction and development. Urban safety drainage A series of problems arose. For example, the sidewalks in urban areas and the impermeable ground of parking lots prevent rainwater from infiltrating, shortening the formation time of urban flood peaks, increasing the total amount and flow velocity of floods, making urban roads impermeable to become the main flood path, and low-lying urban areas are more prone to flooding. The formation of waterl...
