[0042] Example 1 Method for producing aerated concrete with waste incineration slag: The aerated concrete composition contains 57% fly ash, 20% quicklime, 10% P.0.42.5 ordinary Portland cement, 3% gypsum, 10% Waste incineration slag.
[0043] The total water to material ratio is 0.60-0.70, and the mixing water is 60℃ warm water. Add water to fly ash to make a slurry, stir for 3-4 minutes, add cement, stir for 3-4 minutes, add gypsum, stir for 2-3 minutes, add quicklime, stir for 2-3 minutes, pump to the pouring truck and stir the slurry In the tank, turn on the main mixer of the pouring vehicle for two-stage mixing. Add the measured waste incinerator slag, stir for 30-50s, pour it into the mold to generate gas, and let it stand at 60°C for 2 hours, then cut into pieces. Put it into the autoclave, autoclave at 170-180℃ and 0.8-1.2MPa pressure, and leave the autoclave at a constant temperature for 8-10 hours.

[0045] Example 2 Method for producing aerated concrete with waste incineration slag: The aerated concrete composition contains 57% granulated blast furnace slag, 20% quicklime, 10% P.0.42.5 ordinary Portland cement, 3% gypsum, 10 % Waste incinerator slag.
[0046] The total water to material ratio is 0.60-0.70, and the mixing water is 60℃ warm water. Add water to the granulated blast furnace slag to make a slurry, stir for 3-4 minutes, add cement, stir for 3-4 minutes, add gypsum, stir for 2-3 minutes, add quicklime, stir for 2-3 minutes, and pump until the slurry is poured. In the mixing tank, turn on the main mixer of the pouring vehicle for two-stage mixing. Add the measured waste incinerator slag, stir for 30-50s, pour it into the mold to generate gas, and let it stand at 60°C for 2 hours, then cut into pieces. Put it into the autoclave, autoclave at 180-190℃ and 1.0-1.2MPa pressure, and leave the autoclave at a constant temperature for 6-8 hours.

[0048] Example 3 Method for producing aerated concrete with waste incineration slag: The aerated concrete composition contains 38-42% quartz sand, 30-32% slag, 18-20% P.0.42.5 ordinary Portland cement, 10 % Garbage incinerator slag, and appropriate amount of gas generation regulator.
[0049] The total water to material ratio is 0.30-0.50, and the mixing water is 60°C warm water. Mix the slag, quartz sand and dry cement powder evenly, beat the slurry and mix it evenly, stir for 3-4 minutes, pump it into the slurry mixing tank of the pouring vehicle, turn on the main mixer of the pouring vehicle, and perform two-stage mixing. Add the measured waste incinerator slag, stir for 15-30s, pour the mold into the mold, and let it stand for 2 hours at a temperature of 60°C, then cut into pieces. Put it into the autoclave, autoclave at 210°C and 1.5MPa pressure, and leave the autoclave at a constant temperature for 6-8 hours.
