FIELD: building materials, in particular foamglass facing material useful in reconstruction of industrial and civil buildings.
SUBSTANCE: claimed batch contains (mass %): broken glass 58.5-64.5; waste from concentration of apatite-nepheline ores 15.0-22.6; quartz 15.5-17.2; gasifier 3.3-4.0. Waste from concentration of apatite-nepheline ores contains (mass %) nepheline 50.0-65.0; feldspar 2.5-12.0; secondary nepheline minerals 0.5-7.0; egirine 7.0-27.0; apatite 2.0-8.0; sphene 1.5-5.0; titanomagnetite 2.0-5.0. Chalk and carbon black or graphite in ratio of 4.8-8.5:1 are used as gasifier. Barct of present invention makes it possible to reduce density of foamglass facing material by 1.25 times and decrease its thermal conductivity by 1.27 times without losses of strength, water absorption, and frost resistance.
EFFECT: foamglass facing material with reduced and density.
