Feasibility of using pozzolanicity tests to assess reactivity of wood biomass fly ashes

open access: yesGradevinar, 2021
Pozzolanic activity of materials can initially be assumed from the quantity of the pozzolanic oxides SiO2, Al2O3 and Fe2O3. Some of the methods for assessing pozzolanic reactivity of materials include measurement of CaO consumption (Frattini test ...
