This study investigates the use of metakaolin as a partial replacement for cement in concrete, ranging from 0% to 30% with an increment of 5% metakaolin a total of seven mixes is used in this study. In addition to its glass fibers are used to improve the properties of concrete from 0.5 to 2% with an increment of 0.5%. The primary objective is to evaluate the effects of metakaolin and glass fibers on the mechanical properties and durability of concrete. A comprehensive experimental program was conducted to measure various parameters, including compressive strength, tensile strength, and flexural strength. The experimental results were then compared using a numerical approach, specifically Analysis of Variance (ANOVA), to determine the statistical significance of the observed changes. Results indicate that 20% metakaolin replacement and 1.5% glass fiber content yielded the most favorable outcomes, significantly enhancing both compressive, tensile, and flexural strengths compared to other replacement levels. The ANOVA analysis confirms the statistical significance of these improvements, highlighting the optimal replacement percentage for maximizing concrete performance. The study concludes that metakaolin and glass fibers can serve as an effective supplementary cementitious material, offering improvements in concrete strength and durability while promoting sustainability.
