FIELD: chemistry.
SUBSTANCE: method relates to concrete products preparation (slabs, blocks) at freezing temperature. The method of concrete products preparation includes dosing of cement, filler material, water, antifreeze additive, preparation of concrete mixture and placing of concrete and maturing at freezing temperature. The particles, colored with the pigments of cement paste without an antifreeze additive and cooled down to freezing temperature are added into the concrete mixture which is cooled down to freezing temperature. After maturing of the concrete mixture, concrete products are aged at positive temperature till the particles are hardened. The particles take 0.1-10% of concrete mixture's volume.
EFFECT: enhancement of freeze-thaw resistance.
