FIELD: building materials, in particular superlight concrete.
SUBSTANCE: invention relates to production of superlight cellular concrete with porosity of approximately 96 % by using fiber disperse reinforcing. Cellular concrete is obtained by agitation in turbulent blender of raw mixture containing (mass %) Portland cement 44.11-66.64; microsilica 15.57-29.42; disperse fiber (e.g. chopped glass bundle or basalt fiber or chrysotile-asbestos), pretreated with liquid glass in amount of 1.5-2.5 % in respect to raw mixture, 17.79-26.47; aqueous solution of foaming agent including tempering water over 100 % 0.80-2.50. Mixture is blended up to forming homogeneous colloidal solution.
EFFECT: cellular concrete with reduced density and low heat conductivity.
