• • Investigated the development of high-performance concrete by partially replacing cement with metakaolin in compliance with ASTM standards, focusing on mechanical and durability properties.
• • Achieved higher compressive strength at 28 and 56 days, along with reduced permeability, lower chloride ion penetration, and enhanced resistance to sulfate attack.
• • Addressed the slight reduction in workability through the use of superplasticizers, ensuring practical applicability while improving long-term strength and durability.
