Results of the study of the influence of metakaolin on the kinetics of hydration and technical properties of Portland cement are presented. It is shown that as a result of active interaction of meta-kaolin with Са(ОН)2, released during the hydration of Portland cement, the activation energy of the hydration process is reduced by 21.3% in comparison with this characteristic of common Portland cement without additives. Addition of metakaolin to Portland cement improves its properties.
