Chemical foamed concrete and preparation method thereof

[0028] Embodiment 1 (the amount of cement and tailings powder in the two embodiments is not within the scope of the claims and needs to be modified)

[0029] Provide a kind of foam concrete material, comprise cementitious material, blowing agent, compound admixture and water, the mass fraction of described component is:

[0030]

[0031] Its process steps are as follows:

[0032] Mix the cementitious material and compound admixture evenly to form a mixed dry material;

[0033] Stir the mixed dry material and water evenly at 40°C to form cement slurry;

[0034] Add hydrogen peroxide solution (30wt%) to the cement slurry, stir rapidly for 60s, place it in the mold, foam at room temperature, and demould after hardening and molding, and the foamed concrete product is obtained.

[0035] The test data is as follows:

[0036] 28d compressive strength 3.61MPa, bulk density 387kg / m 3 , thermal conductivity 0.06W / (m·k).

[0038] Provide a kind of foam concrete material, comprise cementitious material, blowing agent, compound admixture and water, the mass fraction of described component is:

[0039]

[0040]

[0041] Its process steps are as follows:

[0042] Mix the cementitious material and compound admixture evenly to form a mixed dry material;

[0043] Stir the mixed dry material and water evenly at 35°C to form cement slurry;

[0044] Add hydrogen peroxide solution (30wt%) to the cement slurry, stir rapidly for 60s, place it in the mold, foam at room temperature, and demould after hardening and molding, and the foamed concrete product is obtained.

[0045] The test data is as follows:

[0046] 28d compressive strength 3.59MPa, bulk density 390kg / m 3 , thermal conductivity 0.069W / (m·k).
