Coarse aggregate is one of the basic components of concrete and occupies the largest volume in the mixture (70-75) % [1]. Therefore, it significantly influences the concrete mixture design and properties such as strength, maximum size, shape and water absorption which affect the water demand and the amount of fine cement and fine aggregate in the concrete mixture. This study aims to investigate the effect of utilization of Zliten, Sidi-Alsayeh and Greenilia sand on the compressive strength of normal and self-compacting concrete.
