Abstract: Presence of pozzolanic activity is generally evaluated from the sum of “pozzolanic oxides”
SiO2, Al2O3 and Fe2O3. Pozzolanic materials in the cement react with unbonded calcium
hydroxide and form compounds with cementitious characteristics. According to European
standard for coal fly ash EN 450-1:2013 sum of pozzolanic oxides greater than 70% of mass
indicate pozzolanic activity. This study focuses on determination of reactivity of wood biomass
fly ashes (WBA-F) which has potential to be used as cement replacement in the cement
mixtures. In this paper three different methods were used in order to analyse pozzolanic
reactivity of fly WBAs as a potential supplementary cementitious material (SCM).
