Abstract : This article presented the influence of hybrid cement (HPC) replacement, sand-to-binder ratio, sodium
silicate-to-sodium hydroxide solutions (Na2SiO3-to-NaOH ratio) and liquid alkaline-to-binder ratio on compressive strength
of high calcium fly ash (FA) geopolymer mortar. The FA was replaced with HPC at the ratios of 100:0, 90:10, 80:20and
70:30.The sand-to-binder ratioof 0.5, 1.0, 1.5,Na2SiO3-to-NaOH ratios of 1.0, 2.0, 2.5,and liquid alkaline-to-binder ratios of
0.45, 0.55, 0.60, 0.65,were also tested.Constants14M NaOH concentration was used in all mixes.Test results indicated that the
compressive strength tended to increase with increase of HPC replacement. The compressive strength of geopolymer mortars
at sand-to-binder ratiosof 0.5, 1.0, liquid alkaline-to-binder ratios of 0.45, 0.55 and Na2SiO3-to-NaOH ratio of 2.5, were the
best results. Therefore, all of FA geopolymer mortar containing HPC with different sand-to-binder ratio, liquid
alkaline-to-binder ratio, Na2SiO3-to-NaOH ratio meet the requirement of chemical anchorage except Na2SiO3-to-NaOH ratio
of 1.0.
