Abstract

The present paper explores the comparative study of the geopolymer paste resulting from different alkali activations. In this experimental study, four series of geopolymer pastes differing in the alkali activation were manufactured by activating low calcium fly ash. These activators were subjected to a certain temperature of 35 °C for duration of 24 h. After casting of the specimens, activated by those activators, they were subjected to 85 °C for 48 h. The performance of the geopolymer specimens were investigated on the basis of workability and strength. Scanning electron microscopy along with EDAX was also conducted to predict microstructural and mineralogical changes.
