FIELD: chemistry.
SUBSTANCE: invention relates to preparation of concrete mixtures for making construction articles and structures.The concrete mixture, which contains cement, crushed cement clinker as coarse and fine aggregate and water, contains said coarse aggregate fraction of 10-40 mm, with the following ratio of components in wt %: cement 20.0-25.0, said coarse aggregate 22.0-28.0, said fine aggregate 28.0-37.0, water 20.0-25.0. The cement used can be cement obtained by grinding said cement clinker which is used as coarse and/or fine aggregate.
EFFECT: high water resistance.
