FIELD: technological processes.
SUBSTANCE: present invention relates to hydraulic binder involving the parts by weight: (a) from 20 to 60 parts of portland cement clinker; (b) 20 to 40 parts of slag; and (c) from 5 to 60 parts of inorganic material different from the clinker and slag; wherein sum of (a), (b) and (c) equals 100 parts; while binder additionally contains slag activator including on 100 parts of the sum of (a) and (b): from 1.4 to 6.55 parts of alkali metal salt in an equivalent of Na2O; and from 1.1 to 11.0 parts of calcium sulphate in an equivalent of SO3. Invention also relates to hydraulic composition and method of its production, to shaped product and use of the hydraulic composition. Invention is developed in subclaims.
EFFECT: strength increase during 24 hours after preparation and reduced carbon dioxide emission after 28 days.
