Effect of NaOH Concentration on the Strength of Non Sodium Silicate Fly Ash Geopolymer

The current work presents the effect of alkali concentration on fly ash based geopolymer material. In this work geopolymer material was prepared with a fixed Si/Al ratio (1.85: 1) and varied solid to water ratio and NaOH concentration. All samples were tested to establish the role of alkali on the s...
