Zusammenfassung:FIELD: preparation of mortars and concretes similarly to portland cement. SUBSTANCE: proposed binder contains one of the following difficultly soluble oxides in addition to portland cement: MnO2 or CuO or PbO at preliminary electron beam modification by flux of accelerated electrons in range of absorbed doses of 50 to 200 kGy at the following ratio of components, mass-%: portland cement, 98-99; oxide modified by flux of accelerated electrons, 1-2. EFFECT: enhanced strength at temperatures below zero. 1 tbl
