FIELD: manufacture of building materials.
SUBSTANCE: invention provides novel mineral binder manifesting simultaneously quick hardening and resistance to sulfates, which can be used in construction of marine structures as well as structures operated in mineralized water. Manufacture of bonder comprises firing of Portland cement raw mix followed by further grinding of Portland cement clinker together with gypsum cement added. Firing is carried out in reductive medium to reduction degree α = 0.2-0.2, after which resulting clinker is quenched in water from 1450°C. Addition of gypsum cement does not exceed 3.5 wt % (on conversion to SO3) and provides specific surface 2800-3000 cm2/g.
EFFECT: expanded application possibilities.
