The Solution of Environmental and Practical Problems When Using Waste from Aluminum Production
摘要
The waste generated in the process of aluminum scrap remelting contains a significant amount of pure aluminum, aluminum oxide and magnesium aluminate, which are of great importance in the calcining and non-calcining technology for the production of building wall materials. It has been established that the introduction of aluminum containing waste in an amount of 10–20% into the mass based on high-melting clay during firing in the temperature range of 1000… 1100 °C contributes to the formation of ceramic bricks with different porosity, which expands the field of use of synthesized ceramic composites, including as clinker bricks. It has been found that the reacting capacity of the aluminum production waste is inferior to the porization of the concrete mix when using aluminum paste, but with the appropriate quantitative selection of components can provide the necessary properties. The research carried out solves the ecological problem of utilization of bypassing product in the large tonnage construction technologies, saving expensive and scarce natural raw materials, and also has great practical significance in expanding the range and scope of construction materials.
