This paper presents the results of studies of the effect of the degree of dispersion of mineral powders of natural and technogenic origin on the properties of cement alkaline dough. The dependences of the change in the total specific surface area on the duration of grinding have been studied, and the optimum grinding time for raw materials has been revealed. The developed formulations of binding alkaline binders, using mineral powders and waste from the cement industry, are distinguished by

And the obtained regularities of the influence of the degree of dispersion on the properties of the binding binder "mineral powder - Na2SiO3", will make it possible to create strong and durable artificial building composites that compete with concretes on Portland cement. This work was supported by the project No. 05. 607.21.0320. "Development of innovative structural composite materials based on clinkerless binders of alkaline activation using off-grade natural and secondary raw stuff" in the frame of Federal target program "Studies and developments in the prioritized fields of development of R&D complex of Russia for the years 2014-2020".
