Water-permeable brick prepared from serpentine tailings and construction waste and preparation method thereof

Abstract

A water-permeable brick prepared from serpentine tailings and construction waste and a preparation method thereof are disclosed. The serpentine tailings and construction waste are adopted as raw materials and subjected to steps of crushing, sieving, grading, compression molding by utilizing an efficient adhesive and solid waste particles, and finished product curing, and the prepared unfired water-permeable brick has indexes superior to those stipulated by national standards. The serpentine tailings and construction waste which are solid waste can be fully utilized, the additional value of thesolid waste is greatly improved, resource recycling of the solid waste is achieved, site resources occupied by landfill are reduced and the brick has important economic, social and ecological environmental protection 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...

AI Technical Summary

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.
