Iron ore tailing powder sintered permeable square brick and preparation method thereof
The invention discloses an iron ore tailing powder sintered permeable square brick and a preparation method thereof, and belongs to the field of comprehensive utilization of iron ore tailing resources and building materials. According to the method, 50-70% of iron ore tailing powder, 30-50% of network materials and 2-6% of additives are mixed, added with water and uniformly stirred to obtain mixture containing 7-9wt% of water, the mixture is aged for 48h at room temperature, the aged mixture is formed by pressing at 100-160T, the formed product is dried for 6-8h at the temperature of 120-180 DEG C, fed into a kiln, preheated for 7-10h, sintered for 1-2h at the temperature of 1100 DEG C, insulated for 1h at the temperature of 1080-1100 DEG C and cooled for 9-11h to obtain the iron ore tailing powder sintered permeable square brick, and the percent is weight percent. According to the invention, sintered permeable square brick is prepared from iron ore tailing powder by sintering, the resources are saved, tailings are comprehensively utilized, energy is saved, environments are saved, and iron ore tailing powder is a rejected material, is low in cost and can be widely used for various building materials.
