This study examines the effects of fly ash, metakaolin, and fibres (0 to 1) for a water cement ratio of 0.32 on the formation of ternary blended M60 grade concrete at various percentages (0, 5, 10, 15, and 20) of cement replacement. At the age of 28 days, concrete samples were evaluated for mechanical properties like compressive and flexure strength. Entroy and Shaklock Method is used to produce mix design for high-strength concrete M60. To determine the criteria for durability, the Chloride Permeability Test was conducted. Metakaolin and fly ash integration have significantly enhanced the mechanical and durability properties of high-strength concrete. Further models have been created for charge, compressive strength, and flexure strength using independent variables such metakaolin, fly ash, and fibre replacement. Good precisions and correlations between models and experimental data are shown.
