The present invention is 30 to 70% by weight of hot phosphate gypsum and / or 30 to 70% by weight of the dried granite stone powder and / or dried at a temperature of 150 ℃ to 800 ℃ to stabilize the pollutants impregnated with moisture removal 30 to 70% by weight of dried waste limestone as the main material, 20 to 40% by weight of cement, yellow or kaolin, feldspar 2 to 10% by weight, foaming agent (alumina powder, zinc powder) 0.01 to 0.5% by weight, 2 to 5% by weight of foaming catalyst (quick lime and carbonate), 0.01 to 5% by weight of anti-separation stabilizer (methylcellulose, wood flour or rice husk powder), 0.5 to 3% by weight of concrete strength reinforcement, 3 to 15% by weight of tensile strength reinforcement Dry mixed and then mixed and agitated 50 ~ 85% water of the mixed mortar weight at the construction site to maintain a uniform turbidity, 20 minutes to 50 minutes after the complete foam group is formed non-flammable, heat insulation, Insulation, absorption. It is to provide a construction method of foamed concrete mortar having a sound insulation function. |
