Modern production of Portland cement can safely be classified as resource- and energy-intensive, in addition to the main pollutants of the environment, and to reduce environmental tensions it is necessary to look for a replacement for this binder. Analyzing the results of many years of research, we can state that alkaline metal oxides contribute to the synthesis of analogues of traditional hydraulic binders, and the necessary condition is the presence of an alkaline environment with a fairly high pH for the hydration reactions of silicate and aluminosilicate component of the binder. Clinker-free silica-activated cements have a whole set of improved specific properties and can be successfully used in the production of high-strength, quick-hardening, low-thermal, cold-resistant, heat-resistant, hydraulic and corrosion-resistant concrete. The paper presents specific features of alkaline cements obtained by alkaline activation of aluminosilicate mineral additives of different genesis allowing synthesizing hydroaluminosilicate zeolite phase, which determines the acid resistance of the cement stone, and makes it possible to obtain concrete products to work in an acid environment. The proposed technology for obtaining alkaline binder contributes to improving the efficiency of clinker-free construction composites, by reducing the cost, improving the physical and mechanical properties of the final product and expanding the raw material base of the clinker-free technology.
