Effect of molarity of naoh on strength of geopolymer mortar

Geopolymers have received considerable attention due to their properties and applications as environmentally friendly alternatives to ordinary Portland cement. Geopolymer mortar (GPM) is an emerging alternative to ordinary Portland cement mortar (OPCM), and is produced via a polycondensation reaction between aluminosilicate source materials and an alkaline solution. As a relatively new material, many engineering properties of geopolymer mortar are still undetermined. In this study, the compressive strength, have been studied experimentally. A total of 12 geopolymer mix mortar were tested for the above mentioned characteristics, the results indicate that the combination of the above constituents at 90 oC has a positive impact on the strength of geopolymer mortar .The experimental data was analyzed by an analysis of variance (ANOVA) utilizing MINITAB16 statistical software. This method establishes the magnitude of the total variation in the results and distinguishes the random variation from the contribution of each variable. A conventional level of significance (p < 0.05) was used for the statistical analysis.
