Abstract

The purpose of this study was to investigate the potential utilisation of silica fume and eggshell powder as cement replacement for concrete production. Cement was replaced using two percentages of silica fume (15 and 20%) combined with three percentages of eggshell powder (5, 10 and 15%) by weight of cement. The workability, compressive, and splitting tensile strengths of concrete incorporating silica fume and eggshell powder were analysed. The results demonstrated that the workability of concrete reduced as silica fume and egg shell powder content increased. Furthermore, compressive and splitting tensile strength increased with the total combined content of silica fume and eggshell powder up to 25%. It was also observed that 15% silica fume combined with 10% eggshell powder cement replacement achieved the maximum compressive and splitting tensile strengths. The replacement of cement with a combination of silica fume and eggshell powder of greater than 25% led to a decrease in compressive and splitting tensile strength.
