From food wastes, there are many materials that can be used as building materials like eggshells. This paper examined the effect of ultra-fine eggshell powder (UFESP) as a partial cement replacement by (0–25% with 5% increments) in weight on fresh and compressive strength of sustainable Self-Compacting Concrete (SCC) with a constant water to binder ratio and binder content of 0.38 and 450 kg/m 3 , respectively. All mixes were tested for fresh properties of slump flow diameter and time, V-funnel time, L-box height ratio, dry density and compressive strength. The results of fresh properties for all mixtures satisfied the requirements recommended by EFNARC for SCC. However, the compressive strength of SCC mixes increased by the addition of UFESP up to 15% compared to the control mixture, then decreased and recorded 42 MPa for the mix containing 25% of UFESP. Meanwhile, the dry density decreased as UFESP utilization increased in the mixtures.
