The given research is devoted to the studies of morphology, particle size and pozzolanic activity of different supplementary cementing materials (SCM) – thermally treated clays as well as waste products – coal ash, waste glass powder, timber and barley ashes. Different properties of SCM have been analysed: specific surface area, surface morphology, particle size distribution, chemical composition and lime-combining capacity in the reaction with Ca(OH) 2 . The obtained results have indicated that micro additives with larger specific surface are more reactive.
