FIELD: construction.
SUBSTANCE: mixture to make heat insulation includes lime and siliceous component in conversion to CaO and SiO2 at the ratio of 0.2-2 and a filler in the form of wollastonite of amorphous structure. Additionally basalt fibre with length of 13-15 mm is added to wollastonite of amorphous structure at its ratio to diameter making from 8000 to 9000. Ratio of mixture components is as follows, wt %: filler - mixture of wollastonite of amorphous structure with basalt fibre 50-60, lime and siliceous component 40-50.
EFFECT: production of heat insulation material with low shrinkage in a wider temperature range, high temperature resistance.
