Through an optimization procedure using Minitab software, the optimum waste eggshells-ash powder (WESP) content is used in reinforced concrete. The following percentages of WESP, 0%, 2.5%, 5%, 7.5%, 10%, 12.5%, and 15%, have partially replaced natural fine aggregate. With increasing WWESP, it was discovered that compressive strength, elastic modulus, impact-resisting, and bonding strength between steel bar and concrete increased for WWESP% up to 7.5%. The optimal WESP content was optimized using the Minitab software to be 3.64%.
Key words: Bond strength / eggshell ash / impact resistance / optimization
