FIELD: chemistry.
SUBSTANCE: invention relates to field of construction and can be used as dry plaster mixture, intended for heat-insulating covering of external and internal sides of walls of building constructions. Composition of heat-insulating plaster mixture contains, wt %: slack lime 3-7, expanded perlite 2-4, limestone powder 20-28, foam glass 15-25, methylcellulose 0.1-0.2, foaming agent based on sodium lauryl sulfate 0.015-0.045, water-soluble additive based on modified starch ester 0.03-0.08, polypropylene fibres 0.02-0.1, redispersible powder of copolymer of vinylacetate and ethylene 2-5, Portland cement 30-36, quartz sand 10-20.
EFFECT: increased efficiency of heat protection, ensuring stability of thermophysical and physicomechanical parameters of plaster layer for is entire guaranteed service term.
