Description
Summary: Objectives The creation of clinkerless cements that do not require high-temperature processing and significant natural resources, at the same time as exhibiting good technical parameters, seems to be an important research task. Cements of alkaline instillation, in which alkaline metals play an active role, are capable of interacting with minerals of aluminosilicate nature forming strong and insoluble compounds. Methods Concrete composites from binding substances activated by alkaline were developed on the basis of Russian and foreign experience of using cinder slag composites in construction. Results In this work, energy-dispersion microanalysis of the developed clinkerless compositions based on alkaline silicate sodium solutions from silica-containing rocks was carried out. Conclusion Formulations of clinkerless cements based on high-dispersal powders of different natures mixed by the alkaline solution obtained using the wet technique at temperatures of up to 95 °C and atmospheric pressure are proposed. This technology will expand the use of alkaline cements, thus leading to the development of concrete having desired properties.
