Method for preparing high-strength sintered water permeable brick from vanadium-titanium-iron tailings and reservoir bottom mud
In order to effectively utilize vanadium-titanium-iron tailings, gold tailings and reservoir bottom mud and change waste into wealth, the invention provides a method for preparing a high-strength sintered water permeable brick by utilizing the vanadium-titanium-iron tailings and the reservoir bottom mud, and the method comprises the following steps: S1, pretreating the reservoir bottom mud; S2, pretreating coal gangue; S3, preparing aggregate of a water permeable brick; S4, preparing a binding agent; S5, conducting aging; S6, conducting compression molding; and S7, conducting sintering molding. According to the method, the vanadium-titanium-iron tailings, the gold tailings, the coal gangue and the reservoir bottom mud can be effectively utilized, the purposes of energy conservation and environmental protection are achieved, meanwhile, waste can be turned into wealth, and solid waste has high economic value. According to the high-strength sintered water permeable brick prepared by the invention, the compressive strength, the water permeability coefficient and the water retention far exceed the highest indexes required by 'JCT945-2005-water permeable brick' and 'GB/T25993-2010 water permeable pavement bricks and water permeable pavement slabs', and the high-strength sintered water permeable brick has the characteristics of high strength and high water permeability.
