FIELD: chemistry.
SUBSTANCE: invention relates to a hydraulic binder comprising: at least 70 wt. % of a solid mineral compound consisting of at least one mixture of silicon oxide, aluminium oxide and alkali-earth metal oxides, wherein total content of CaO and MgO is at least 10 wt. % of solid mineral compound, and an activating system, at least 30 wt. % of which is a salt of phosphoric acid. Also described are construction products obtained from a mortar composition containing such a binder. Invention also relates to a composition for concrete or mortar and to construction products made from concrete or mortar.
EFFECT: technical result is acceleration of setting and/or hardening of binder, high strength of binder.
