Mechanical strength variation of zeolite-fly ash geopolymermortars with different activator concentrations
Öz: Zeolite is of a significance for geopolymers as it is a natural precursor and does notrequire additional heat treatment for activation. However, aluminosilicates sourcedfrom natural sources require additional handling for the best use of exploitation. In this study, geopolymers were synthesized by binary use of zeolite and fly ash as mainbinding material and sodium silicate and sodium hydroxide as alkaline activator. Theinfluence of alkaline activator ratios and sodium hydroxide concentrations on thecompressive strength and flexural strength of the zeolite-fly ash based geopolymerswere studied. In this research, zeolite-fly ash based geopolymer mortars were pro duced by using 50% of natural zeolite (clinoptilolite) and 50% of C-type fly ash. Fourdifferent activator ratios ($Na_2SiO_3$/NaOH: 1, 1.5, 2 and 2.5) and two sodium hydrox ide molarities (10M and 12M) was utilized to activate zeolite and fly ash in order todetermine the effect of these parameters on the mechanical strengths of the pro duced geopolymer mortars. The results indicated that as the alkaline activator ratioand NH molarity were increased the compressive strength of the zeolite-fly ash basedgeopolymers also increased. The maximum compressive and flexural strength valuesobtained after 28 days of curing were 20.1 MPa and 5.3 MPa respectively and corre sponds when used activator ratio of 2.5 and sodium hydroxide concentration of 12molarity. The obtained results indicated that both the alkaline activator ratio and so dium hydroxide concentration affected the compressive and flexural strengths of ze olite-fly ash based geopolymer mortar specimens.
