A composition for the production of unburnt heat-insulation articles relates to building and can be used for heat insulation of industrial furnaces and other heat aggregates, used in metallurgy, energetic, machine building and petrochemical industry. The invention allows producing durable unburnt heat-insulation articles with increased softening coefficient at 1000 °C. Composition contains weight %: lightweight coal clay with imaginable density is not above 0.4 g/cm– 40-67, perlite sand – 3-10, disthenesillimanite concentrate with prevailing grain size less than 100 micrometers – 5-15, high-alumina cement – 24.998-34.995, surfactant – 0.002-0.005. |
