The purpose of the work is the development of applied and technological solutions for the production of alkaline cements with controlled shrinkage and high strength for high-consistency concretes with specified properties and durability. As a result of the research work, optimum compositions of alkaline cements with specified properties were obtained and on the basis of them were developed mortars and concretes, the characteristics of which correspond to the given conditions of application.
