FIELD: manufacture of building materials.
SUBSTANCE: invention provides binder containing Portland cement (69-73%), manganese oxide treated by accelerated electron beam at optimum absorbed dose value 50-200 kGr (1-2%), and tempering water treated by accelerated electron beam at optimum absorbed dose value 15-40 kGr (26-29%). Binder can be used when manufacturing mortars and concretes under lowered- and negative-temperature curing conditions.
EFFECT: increased strength under low-temperature curing conditions.
