FIELD: technological processes.
SUBSTANCE: invention relates to the production of a cement clinker substitute by providing starting material in the form of a natural and/or synthetic zeolite-containing pozzolan and clays and carrying out heat treatment of the starting material to produce a cement clinker substitute in the temperature range 500–1,200 °C, wherein before and/or during the heat treatment of the starting material, at least one flux is added, which reduces the internal surface area of the cement clinker substitute. Invention is developed in dependent claims of the invention.
EFFECT: reduction in water consumption, increase in early strength.
