Embodiment 1
[0048] Such as figure 1 As shown, the aluminum ash, calcium carbide slag, desulfurized gypsum, and iron tailings are dried until the moisture content is not greater than 5%. The coal gangue and iron tailings are pulverized, and mixed with aluminum ash, carbide slag, and desulfurized gypsum. In terms of solid matter, iron tailings account for 8 parts by weight, coal gangue accounts for 22.55 parts by weight, desulfurized gypsum accounts for 19.05 parts by weight, and calcium carbide The slag accounts for 35 parts by weight, and the aluminum ash accounts for 20 parts by weight. After the materials are blended, they are ground and homogenized. After grinding, they are directly transported into the rotary kiln for calcination. The calcination temperature is 1250°C and the calcination time is 70 minutes. The main phases of the clinker after firing are calcium sulfoaluminate and dicalcium silicate. Take the above base material, add 0.5% of the mass of the base material as quick-s...
Embodiment 2
[0050] Dry aluminum ash, carbide slag, desulfurized gypsum, and iron tailings until the moisture content is not greater than 5%. The coal gangue and iron tailings are pulverized, and mixed with aluminum ash, carbide slag, and desulfurized gypsum. In terms of solid matter, iron tailings account for 10 parts by weight, coal gangue is 20 parts by weight, desulfurized gypsum is 13 parts by weight, and calcium carbide The slag is 30 parts by weight, and the aluminum ash is 15 parts by weight. After the materials are blended, they are ground and homogenized. After grinding, they are directly transported into the rotary kiln for calcination. The calcination temperature is 1300°C and the calcination time is 80 minutes. Take the above base material, add 1% quick-setting agent, 1.5% expansion agent, and 0.5% dispersant of the base material mass, and take another 96 parts of water, the quality of each 2 parts of water is the same as that of the above base material, and mix thoroughly Pr...
Embodiment 3
[0052] Dry the aluminum ash, carbide slag, and desulfurized gypsum until the moisture content is not greater than 5%. The coal gangue and iron tailings are pulverized, and mixed with aluminum ash, carbide slag, and desulfurized gypsum. In terms of solid matter, the iron tailings account for 15 parts by weight, the coal gangue is 25 parts by weight, the desulfurized gypsum is 18 parts by weight, and calcium carbide The slag is 33 parts by weight, and the aluminum ash is 17 parts by weight. After the materials are mixed, they are ground and homogenized. After grinding, they are directly transported into the rotary kiln for calcination. The calcination temperature is 1270°C and the calcination time is 75 minutes. Take the above base material, add 0.7% of the mass of the base material as quick-setting agent, 1% of expansion agent, and 1.5% of dispersant, and take another 96.5 parts of water, the quality of each 2 parts of water is the same as that of the above-mentioned base mater...
