Abstract

The results of pozzolanic activity determination using DTA-TG method are presented. This feature was characterised by Ca(OH)2 residue determination in cement pastes admixtured with siliceous earth, consuming the calcium ions from hydrolysis of cement clinker minerals. The rate of pozzolanic reaction was thus estimated. Some results for fly ash containing pastes were also given.
