Abstract
On the possibility of physical and chemical control of the self-stress kinetics of the expansive binders
Domestic construction materials industry produces expansive binders providing the concrete self-stress up to2MPa. A hypothesis on the catalytic role of lime in the formation of the active ettringiteis introduced. On the base of the hypothesis a proposal of the self-stress kinetics optimization with sulfate-containing mineral supplements, neutralizing lime in the early stages of the cement stone structure formation is given.
