Sažetak
Presence of pozzolanic activity is usually 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) which is used as cement replacement in the cement mixtures. In this paper three different methods were used in order to analyse hydraulic /pozzolanic reactivity of fly WBAs as a potential supplementary cementitious material (SCM).
