METHOD OF PRODUCING CONSTRUCTION MATERIAL Russian patent published in 2017 - IPC C04B28/26 C01B33/32 C04B111/20 C04B111/23 C04B111/27 C04B111/76 

FIELD: construction.

SUBSTANCE: invention relates to construction and relates to industry of construction materials, particularly, to production of any types of construction articles, road surfaces, and can be used in residential and industrial construction, construction of roads, in casting, chemical production and other fields. Method of producing construction material involves mixing silica and 5% alkaline solution at a ratio of dry and liquid components of 1:1 with simultaneous exposure of mixture to an electromagnetic field until complete dissolution of silica, adding obtained solution in amount of 4 % to 8 % of total volume of mixture to silica-containing raw material, including 5–10 % or 15 % cristobalite of total volume of mixture, then stirring mixture until complete wetting of silica-containing raw material, moulding articles from obtained mixture and processing by drying at a temperature of 40 °C to 80 °C or by steaming article at a temperature of 90 °C–120 °C, or by exposing article to microwave radiation. Invention is developed in subclaim.

EFFECT: technical result is simplification of production of articles, high heat resistance, water resistance, strength, acid resistance, low water absorption.
