Effect of synthesizing parameters on workability and compressive strength of Fly ash based Geopolymer mortar

Geopolymer is known for its durability and environmental sustainability. The findings of this research paper are based on the experiments conducted on geopolymer mortar synthesized from locally available fly ash. Various engineering properties are highlighted. Influence of processing parameters such as Fly ash/Sand ratio, SiO₂/Na₂O ratio, and Water/Fly ash ratio on workability and compressive strength are studied which may be useful to develop mix design methodology. Pore size distribution and total pores volume are appreciated by Mercury Intrusion Porosimetry (MIP) and their influence on compressive strength. Scanning electron microscopy (SEM) along with Energy dispersive X-ray spectroscopy (EDX) was done for micro-structural and elemental analysis.
