Abstract : Compressive strength tests were conducted in accordance with standard procedures at the SEA PORTS CORPORAT (SUDAN) ENGINEERING TEST LAB. The results demonstrated that all mixes achieved high strength classification (above 40 N/mm²), with the 20% pozzolana mix yielding the highest average 90 days compressive strength of 46.6 N/mm², compared to 40.3 N/mm² for the reference mix representing an improvement of approximately 16%. These findings confirm that locally available pozzolana can be effectively utilized as a cement replacement material to enhance concrete compressive strength, offering both structural and economic benefits.

Keywords : Cement, Pozzolana, Chemical Composition, Compressive Strength, Workability.
