Example Embodiment
[0025] Example 1:
[0026] 1. The blast furnace slag taken from the Shaoguan Steelmaking Plant, whose basicity coefficient, activity coefficient and prime number coefficient are all in line with the national Class I quality, is pre-pulverized to a particle size of less than 200 mesh (74 microns).
[0027] 2. Take 1.3kg of the above-mentioned pulverized blast furnace slag, and 7.6kg of lead-zinc tailings from Qujiang Fankou, Shaoguan City, Guangdong Province, with 0.4kg of red mud produced by the sintering method of Zhengzhou Aluminum Plant and 0.5kg of weathered clay as auxiliary 0.1kg of phosphogypsum with a particle size of less than 45 microns is used as an activator, and 0.03kg of sodium lignosulfonate is used as a dispersant. First dissolve the dispersant in 1.2kg of water to be added, mix the dry powder and water with a horizontal coulter mixer or a high kneading mixer, mix evenly and pour into the mold, use a hydraulic brick machine to adjust the pressure to 20.0 Mpa, press...

[0033] Example 3:
[0034] 1. The blast furnace slag taken from the Shaoguan Steelmaking Plant, whose basicity coefficient, activity coefficient and prime number coefficient are all in line with the national Class I quality, is pre-pulverized to a particle size of less than 200 mesh (74 microns).
[0035] 2. Take 1.1kg of the above-mentioned pulverized blast furnace slag, 7.8kg of lead-zinc tailings from Fankou, Qujiang, Shaoguan City, Guangdong Province, and 0.9kg of red mud produced by the sintering method of Zhengzhou Aluminum Plant as auxiliary agents, with a particle size of less than 45 0.09 kg of micron phosphogypsum was used as an stimulant, and 0.04 kg of sodium hexametaphosphate was used as a dispersant. First dissolve the dispersant in 1.2kg of water to be added, mix the dry powder and water with a horizontal coulter mixer or a high kneading mixer, mix evenly and pour into the mold, use a hydraulic brick machine to adjust the pressure to 20.0 Mpa, pressurized into a bri...
