Embodiment 1

[0025] Take electrolytic manganese slag from a manganese mining company in Guangxi, mix electrolytic manganese slag, lime, water-quenched slag, and cement clinker in a ratio of 40:3:45:12, and then grind it with SM-500 test mill Cement M, then put cement M, electrolytic manganese slag, 5-10mm waste rock, and water into the mortar mixer according to the ratio of 15:29:40:16, and send it to the brick making machine after stirring for 3 minutes, using LM-02 Extrusion molding is carried out on a digital dynamometer, and a molding pressure of 20MPa is selected. After reaching the molding pressure, the pressure is stabilized for 3 minutes and then unloaded to make brick embryos. Send to the storage site, avoid direct sunlight and rain, and dry naturally for 7 days to become finished bricks. Its compressive strength was measured to be 21.08MPa, reaching the strength standard of unburned bricks.

Abstract

The invention discloses an electrolytic manganese residue baking-free brick and a preparation method thereof. The electrolytic manganese residue baking-free brick is prepared from a cementing agent M,electrolytic manganese residues, waste stone, water and the like through extrusion and curing, wherein the cementing agent M is composed of electrolytic manganese residues, lime, water-quenched slagand cement clinker. The baking-free brick takes electrolytic manganese residue waste as the main raw material to obtain higher compressive strength and better water resistance, so that the problem that the electrolytic manganese slag is stacked and pollutes the environment is solved, and a novel formula for preparing the baking-free brick is developed.

Description

technical field [0001] The invention relates to an unfired brick, in particular to a method for preparing an unfired brick by using electrolytic manganese slag as a main raw material for its resource utilization, and belongs to the field of solid waste resource utilization. Background technique [0002] Manganese is an important basic material in the national economy and one of the country's important strategic resources. Due to the lack and insufficiency of manganese production technology, 7-8 tons of electrolytic manganese slag should be produced to produce 1 ton of manganese. At present, my country's proven manganese ore reserves are more than 600 million tons, so a large amount of electrolytic manganese slag will be produced. The particle size of the manganese slag is ultra-fine and rich in sulfate so that it is difficult to handle. Nowadays, the domestic electrolytic manganese slag is mainly stored naturally, resulting in Occupying a large amount of land, often years of ...
