Abstract: A lightweight foam concrete composition for sound-absorbing materials is provided to have heat resistance and water resistance, retain original performances and shape even after firing, and be harmless to environment. A lightweight foam concrete composition for sound-absorbing materials includes: a powder comprising 40-50 parts by weight of bottom ash powder, 40-50 parts by weight of ordinary portland cement and 2-10 parts by weight of alumina cement, 2-10 parts by weight of anhydrite, and 1-5 parts by weight of slaked lime based on 100 parts by weight of the total powder; 70-90 parts by weight of water based on 100 parts by weight of the powder except for the bottom ash; and 200-300 % by volume of foam based on 100 % by volume of the powder slurry comprising the powder and water. The foam is obtained by diluting 2-4wt%, based on water, of an alkylethersulfate ester salt as a foaming agent with water, and pre-foaming the mixture. Further, a size of the foam is 0.3-1.4mm and an average size of the foam is 1.2mm.
