Abstract

It has been known for decades that geopolymer will significantly replace cement’s function in construction industry. Geopolymer has low creep and shrinkage and a peak compressive strength. That is as per a recent study, geopolymer mortar is made by Fly ash and GGBS. The composition includes (100-60%) GGBS with a 10% substitution of fly ash. Alkali activators used in the research are sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). In the investigation, Na2Sio3 is employed in two different molarities of 4 and 8. The utilised ratios of sodium hydroxide (NaOH) to sodium silicate (Na2SiO3) were 1.5, 2, 2.5, and 3. Investigation and research are done for mortars. Alkali activators’ effects on the molarities of their setting times and characteristics. The 28-day compressive strength varied from 60 to 85 MPa, suggesting that high-calcium fly ash should be used to produce early, high-strength geopolymer concrete. The results revealed that the variables being studied significantly influenced the properties of the geopolymer mortars produced. Increasing either the NaOH concentration or the Na2SiO3/NaOH ratio led to a decrease in workability and setting time

Keywords: Alkaline activator, Workability, Compressive Strength, Molarities, and Geopolymer.
