The ways of reducing CO2 emissions in the cement industry for the implementation of the low carbon development strategy were analyzed. Rational solution to this problem is the technologically optimized blended cements with high volume supplementary cementitious materials of various genesis and fineness. The design of such blended cements achieved by a synergistic combination of the main constituents as granulated blast furnace slag, superfine zeolite, fly ash and limestone, optimization of the their granulometric composition, taking into account their bimodal particle size distribution by volume and surface area that provides their technical, ecological and economic benefits.
