Abstract: The present invention relates to a sustainable concrete composition utilizing Ground Granulated Blast Furnace Slag (GGBS) and Metakaolin as partial replacements for cement in M30 grade concrete to improve mechanical strength, durability, and environmental sustainability. The invention investigates the combined effect of GGBS and Metakaolin at varying replacement levels on the fresh and hardened properties of concrete . Concrete mixes were prepared with different proportions of GGBS and Metakaolin to evaluate their influence on workability, compressive strength, split tensile strength, water absorption, permeability resistance, and durability characteristics in accordance with relevant Indian Standard specifications. Experimental investigations demonstrated that GGBS improves long-term strength and enhances durability through secondary hydration and pore refmement, while Metakaolin contributes to higher early strength and reduced permeability due to its high pozzolanic reactivity and micro-filler effect The combined incorporation of GGBS and Metakaolin produced a synergistic effect, resulting in improved mechanical properties, reduced porosity, enhanced crack resistance, and superior durability performance compared to conventional concrete. The optimum replacement level was identified as approximately 30% GGBS and 10% Metakaolin, which provided balanced improvement in strength, workability, and durability characteristics The invention further promotes sustainable and eco-friendly construction practices by reducing cement consumption, lowering carbon dioxide emissions associated with cement production, and effectively utilizing industrial by-products in concrete manufacturing. Accordingly, the developed concrete composition-provides an environmentally sustainable and high- performance alternative to conventional cement concrete for structural applications.
