The purpose of the work is the development of applied and technological solutions for the production of alkaline cements with controlled shrinkage, the speed of the set of early and vintage strength for use in high-masonry concrete with specified properties and durability. As a result of the research work, the influence of anion-containing additives on the individual deformations of alkaline cements has been investigated and the relationship between self-deformations and processes of cement structure formation has been determined.
