POZOLAN ACTIVITY OF CALCINED CLAYS AND OTHER POZZOLANS USING THE FRATTINI TEST
Original language description
The presented work deals with the determination of pozzolanic activity according to the Frattini test (ČSN EN 196-5) of selected high-temperature fly ash (FA), biomass ash (BMA), calcined clays (CC) fired at a temperature of 600 - 1000°C and SiO2. The results showed that the reactivity of individual substances differs significantly. All FA showed pozzolanic activity, while biomass ash showed significantly worse pozzolanic properties, which, however, is directly related to the high proportion of calcium ions in these ashes. Stachema silica fume with a very high specific surface had excellent pozzolanic properties, while the waste silica did not show pozzolanic properties. By monitoring the effect of calcination temperature on the subsequent reactivity of the selected clay, it was found that the temperature has no significant effect on the reactivity of the clay according to the performed Frattini test. The reduction of reactivity was achieved only at a temperature of 1000 ° C, when mullite was formed in the sample.
