Effect of Sintering Aids on Performance of Manganese Tailings Permeable Bricks

Abstract:

As a kind of sponge city water-permeable material, permeable brick has good water permeability, chemical stability, corrosion resistance and weather resistance. Therefore, the development of permeable brick also broadens the engineering application market for its application. The discharge of a large amount of manganese slag will cause serious environmental pollution, and the problem of manganese tailings accumulation is serious. There is no ideal treatment method at present. In this paper, manganese tailings slag is used as the main raw material to prepare sponge city permeable bricks, thereby turning waste into treasure. Through research, the permeable brick with MgO used as sintering aid has very low compressive strength and good water permeability. CaO used as a sintering aid has high compressive strength and low water permeability. The porosity and water permeability of permeable bricks increase with the increase of CaCO₃, but the compressive strength is opposite. In comparison, the permeable bricks prepared with three different sintering aids, 3% CaCO₃ and 2% MgO as sintering aids have good water permeability and superior compressive strength. The permeability coefficient of the permeable brick prepared with 3%CaCO₃ and 2%MgO as sintering aids is 2.0×10^-2cm/s, and the compressive strength is 1.3MPa.
