Fired brick and preparation method thereof
The invention provides a fired brick and a preparation method thereof. The fired brick mainly comprises the following raw materials in weight part: 40-80 parts of iron tailings, 20-60 parts of gangue, 1-10 parts of an auxiliary agent and 7-25 parts of water. The sum of the weight parts of the iron tailings and the gangue is 100 parts. The sludge and/or the mud tailings is adopted as the auxiliary agent. The fired brick is porous, large in compressive strength and good in weather resistance. The radionuclide content of the fired brick is in line with the national standard requirements. Large amounts of solid wastes in metallurgical mines and industrial waste residues can be fully utilized to prepare novel tailings-based building materials. Therefore, the fuel is saved and resources are fully utilized. The circular economy is developed and the environment is protected.
