Embodiment 1
[0035] Such as Figure 1-6 As shown, a novel lightweight compressive foam concrete, the concrete is prepared by the following raw materials in parts by mass:
[0036] 36 parts of cement, 26 parts of fly ash, 21 parts of lime powder, 13 parts of asbestos fiber, 11 parts of glass fiber, 3 parts of foaming agent, 1 part of calcium stearate, 2 parts of polycarboxylate superplasticizer, 42 parts of water .
[0037] The foaming agent is formed by mixing lauryl alcohol, alcohol ether glycoside, sodium lauryl sulfate, and ammonium carbonate in a mass ratio of 1:1.2:0.8:1.1.
[0038] A method for preparing a novel lightweight compression-resistant foam concrete, the method specifically comprising the following steps:
[0039] Step 1. Add cement, fly ash, lime powder, asbestos fiber, glass fiber, calcium stearate, polycarboxylate superplasticizer and water into the mixer, stir at a speed of 530r / min for 22min, and then add foaming agent , stirred at a speed of 310r / min for 33min to o...
