Inhibitory activity and transformation of mineral additives in testing of cement compositions for alkali expansion

The work reviews the transformation of silica-containing additives (silica fume, metakaolin, precipitated SiO2, and low-calcium fly ash) in the cement stone and cement-sand mortar, aged in tests according to the method close to GOST 8269.0 (a method of testing concrete samples).
