An attempt has been made in this study to investigate the properties of geopolymer concrete while in the fresh state. Fresh properties of geopolymer cement have been studied by varying concentration of sodium hydroxide (NaOH) having concentration 8M, 10M, and 14M. Further, the ratio of Na2 SiO3 to NaOH was kept in the range of 1, 1.5 and 2.5. It has been found that standard consistency decreased significantly and initial and final setting times decreased as the salt concentration of the alkaline solution and of NaOH increased. The compressive strength of geopolymer cement increased with the increase in the concentration of NaOH and with the increase in the concentration of sodium hydroxide. The compressive strength was even higher than conventional concrete at the concentration of 14M.
