The evaluation of the effectiveness of the developed modified concretes and building mortars based on low-carbon multicomponent cements is based on the approach of determining the specific consumption of Portland cement clinker per unit strength and per unit CO2 intensity from the use of the developed compositions. To achieve the maximum technical and environmental effects of modified concretes and mortars, the design of compositions were carried out on the basis of a comprehensive analysis of mathematical models by the criteria of functionality. Experimental studies of the effect of complex modifiers with plasticizing and air-entering action on the technological, physical and mechanical properties of concrete and building mortar have been carried out, which made it possible to increase workability, corrosion resistance, weather resistance and to provide reduced heat of hydration. It is shown that the treatment of cement stone with carbon dioxide is an effective method of increasing the early strength of concrete based on multicomponent cements. Due to the obtained scientific results, the directional formation of the required construction and technical properties of modified concretes class C 8/10 ... C 35/45 was conducted, and a complex of experimental-statistical models of quality indicators of modified building mortars based on low-carbon multicomponent cements was obtained
