Waste brick superfine regenerated active micro-powder and preparation method thereof
The invention discloses a waste brick superfine regenerated active micro-powder and a preparation method thereof. The micro-powder has a specific surface area of more than 600m<2>/kg and a 28d activity index of more than 70%, and can be used as a mortar and concrete admixture. The micro-powder is prepared by taking waste bricks, which have grain diameters of about 3-10cm and are selected from the building waste generated during a house building removal and construction process, as raw materials, and processing through grinding and composite chemical excitation processes. According to the micro-powder and the preparation method disclosed by the invention, superfine grinding and efficient activation for the waste bricks are realized, and a utilization mode with high additional value is provided for the waste bricks.
