POZZOLANIC ACTIVITY OF FLY ASH AND BOTTOM ASH BY FRATTINI TEST AND ELECTRICAL CONDUCTIVITY TEST
Original language description
Pozzolanic activity is an important property of supplementary cementitious materials (SCMs), which plays a fundamental role in determining their suitability for the usage in cements and concretes. This activity is most often determined by the reaction between the aluminosilicate component of pozzolan and Ca(OH)2 under normal conditions. In this work, the pozzolanic activity of fly ash (FA) and bottom ash (BA) from a lignite power plant in the Czech Republic was studied from the perspective of the Frattini test and the electrical conductivity (EC) test. At the same time, the effect of milling on pozzolanic activity was studied. It was found that all FA and BA samples showed pozzolanic activity by Frattini test. The least consumed Ca2+ ions, and therefore the lowest pozzolanic activity, were attested in unmodified FA and BA samples, which at the same time also had the smallest specific surface area value. A continuous EC test for a period of 24 hours confirmed a similar course of the eclectic conductivity decline curves in the observed time for both types of SCMs. © 2023 40th Annual International Pittsburgh Coal Conference, PCC 2023.
