Abstract
The invention discloses a method for preparing steam-pressing bricks from multiple raw mineral materials. The steam-pressing bricks which are prepared from the multiple raw mineral materials are prepared from the following raw materials in parts by weight: 45-50 parts of coal ash, 10-15 parts of tailing, 13-16 parts of electrolytic rock ballast, 12-16 parts of lime and 2-4 parts of composite modified mineral powder. According to the invention, a plurality of mineral substances are compounded and modified, the obtained powder can be well compatible with other raw materials, and the steam-pressing bricks are non-cracking, high in strength, environment-friendly and simple in preparation process.
