PURPOSE: Provided is a composition for foam concrete mortar with incombustibility, heat insulation, and sound absorption and insulation by using waste slaked lime as main material. CONSTITUTION: The foam concrete mortar composition is prepared by dry-mixing 30-70wt.% of waste slaked lime(Ca(OH)2) as main material and auxiliary materials. The main material is waste slaked lime dried at 200-300deg.C to form homogeneous foams. The auxiliary materials comprise 20-40wt.% of cement, 2-20wt.% of yellow earth, kaolin or feldspar, 0.01-0.5wt.% of foaming material such as Al2O3 or Zn, 2-5wt.% of foaming catalysts such as CaO and carbonate, 0.01-5wt.% of separation inhibitor such as methyl cellulose, wood powder or rice hull, 0.5-3wt.% of concrete strength-reinforcing material, and 3-15wt.% of tensile strength-reinforcing material such as sepiolite.
