FIELD: chemistry.
SUBSTANCE: invention relates to a powdered composition of a construction material, preferably dry mortar for industrial production, and especially to tile adhesives, joint filler, putty, waterproofing slurry, repair mortar, levelling mortar, reinforcing adhesives, adhesives for heat-insulation composite systems, mineral plaster, fine putty and seamless floor systems, which contains an ester of A) 2-ethylhexanoic acid and B) an alcohol with a boiling point of at least 160°C. Further, the invention discloses the production of said products, as well as use of esters according to the invention in powdered compositions of construction materials for reducing dust formation. The invention is developed in subclaims.
EFFECT: reducing dust formation, reducing the degree of release of organic compounds during storage and use of construction materials.
