Embodiment 1
[0025] 1. Take 100 grams of sulfoaluminate cement, 30 grams of ceramic micropowder, and 50 grams of water, mix and stir evenly to form a concrete slurry.
[0026] 2. Mix egg yolk, NiCl 2 , xanthan gum, phenol, and water are mixed according to the weight ratio of 100:3:12:1:2.5, and stirred evenly with a high-speed mixer until uniform and dense foam is formed. Take 200mL of the foam and add it into the prepared cement concrete slurry, stir to make the mixture uniform, and cast it into a mold. After 28 days of curing, the dry bulk density that can be produced is 400kg / m 3 , lightweight foam cement concrete with a compressive strength of 0.8MPa and a thermal conductivity of 0.07W / (m.k).
Embodiment 2
[0028] 1. Take 100 grams of sulfoaluminate cement, 30 grams of ceramic micropowder, and 50 grams of water, mix and stir evenly to form a concrete slurry.
[0029] 2. Egg yolk, FeCl 2 , lignosulfonate, benzoic acid, and water are mixed in a weight ratio of 100:5:10:0.5:3, and stirred evenly with a high-speed mixer until uniform and dense foam is formed. Take 400mL of foam and add it to the prepared concrete slurry, stir to make the mixture even, and pour it into a mold. After 28 days of curing, the dry bulk density can be obtained as 320kg / m 3 , lightweight foam cement concrete with a compressive strength of 0.6MPa and a thermal conductivity of 0.065W / (m.k).
