Introduction: Click to view
In recent years, with the rapid development of China's industry, the annual production and cumulative stock of industrial solid waste have increased sharply. Traditional disposal methods such as stacking and landfilling have led to a large area of national land resource waste and serious environmental pollution, which is contrary to our country's concept of building an ecological civilization and harmonious society. Using industrial solid waste as raw material, partially or entirely replacing natural rock materials to develop permeable materials has gradually become a hot topic in this field. This product targets bulk industrial solid wastes such as red mud, coal gangue, fly ash, and low-quality bauxite, researching their application technologies in road permeable materials such as permeable bricks, permeable concrete, and permeable asphalt. The research content includes: analysis of the composition and properties of raw materials, pretreatment technology, processing and manufacturing processes, comprehensive testing of product performance, etc. Based on experimental research, industrialized applications are carried out. The target market is the national road and ecological environmental protection functional material market. There are already 2 related invention patents: 1. A method for producing polymer cementitious materials using red mud and bauxite tailings; 2. A method for producing cement using nickel slag. Additionally, there are 2 other relevant invention patents in application: 1. A method for producing clear bricks using red mud and bauxite tailings; 2. The application of industrial solid waste as an asphalt modifier in porous asphalt pavement materials.
