The research evolves the parametric study of geopolymer paste resulting from various combination of alkali activation. In this experimental study 4 series of geopolymer paste differing in the combination of alkali activation were prepared by activating low calcium fly ash. For every case activators were subjected to a controlled temperature (35oC) for duration of 24 hours. The geopolymer specimens were allowed for a hot curing under 85oC temperature for 48 hours. The parameters like workability, strength and micro-structure were analyzed. Scanning electron microscopy along with EDAX was conducted in a manner to evaluate microstructural and mineralogical aspects of geopolymer specimens.
