ABSTRACT

The present study evaluates the performance of locally sourced and imported aggregates in Somalia, focusing on their impact on the physical and mechanical properties of concrete. Four different aggregates were investigated: Baidoa and Galkayo (locally sourced) and Oman and Dubai (imported). Concrete cubes of 150 mm x 150 mm x 150 mm were prepared and tested under two mix designs, M25 and M30, at curing durations of 7 and 28 days. Five key tests were conducted: compressive strength, slump test, Los Angeles abrasion, water absorption, and sieve analysis. Results indicate that the Oman and Galkayo aggregates exhibited the highest compressive strength in M25, while the Galkayo and Dubai aggregates performed best in M30. The Los Angeles abrasion and water absorption tests revealed that Dubai and Galkayo aggregates had superior durability properties. The sieve analysis showed significant variations in size distribution among the aggregates. Findings provide a foundation for optimizing concrete mix designs in Somalia, balancing availability, cost, and performance. Further research on long-term durability and microstructural properties using SEM analysis is recommended.
