N2 - This study explores the impact of water to binder ratio (W/B), fibre content (fibre%), silica carbide to binder ratio (SiC/B), and superplasticizer to binder ratio (SP/B) on the performance of fibre-reinforced geopolymer composite (FRGC). Using the Taguchi method, the mechanical and durability characteristics of the developed mixes were evaluated by examining each parameter at three levels with an L9 orthogonal array for the experimental setup. This approach enabled a thorough analysis of the influence of each parameter on the properties of FRGC. The experimental program included evaluations of mechanical properties, such as compressive, flexural, and splitting tensile strengths, as well as durability properties assessed through porosity and sorptivity tests. It was found that the lower W/B ratio of 0.28 had the most significant impact on the compressive and flexural strength characteristics, while the optimum fibre% was determined to be 2.5 % for achieving the highest tensile strength. Moreover, analysis of variance accompanied by residual fitting and frequency histogram was conducted to derive mathematical models for accurately predicting the compressive strength exhibiting good correlation with the test results.
