FIELD: chemistry.
SUBSTANCE: invention relates to the field of utilisation of wastes of heat-and-power industry, as well as to the field of obtaining construction materials, in particular expanded clay pebbles, and can be used in industrial, civil and road building, including application in heat-insulation layers, fillers, constrictions, in composition of light concretes as a porous filling agent, in composition of insulation layers and floor screed coats in premises, in road constructions. A raw material mixture for production of expanded clay aggregate contains, wt % by solid phase: montmorillonite clay 52-75, kaolinite clay 15-23, limestone 1-2, technical alumina, sludge of chemical purification of HPP water 7-20.
EFFECT: improvement of heat insulating properties due to reduction of density characteristics with stable strength of expanded clay aggregate, utilisation of technogenic large-tonnage wastes.
