Concrete remains the most widely used construction material globally, with compressive strength serving as its primary performance indicator. In tropical regions such as Cameroon, the availability of ferrallitic (lateritic) soils presents an opportunity to develop cost-effective and sustainable alternatives to conventional concrete. However, the influence of these materials on compressive strength requires systematic evaluation. This study investigates the compressive strength of concrete produced with partial replacement of fine aggregates by ferrallitic materials. Concrete mixes were prepared with laterite replacement levels of 0%, 10%, 20%, 30%, 40%, and 50% at a constant water–cement ratio of 0.50. Standard cube specimens (150 mm × 150 mm × 150 mm) were cast, cured, and tested at 7, 14, and 28 days in accordance with ASTM standards. Results show that compressive strength decreases with increasing ferrallitic content. However, mixes with 10–30% replacement exhibited strength values comparable to conventional concrete, with optimal performance observed at approximately 20% replacement. Beyond 30%, a significant reduction in strength was recorded due to increased porosity and weaker interfacial bonding. The findings confirm that ferrallitic materials can be effectively utilized in structural concrete within controlled limits. The study concludes that partial replacement of fine aggregates with laterite (≤30%) is feasible for structural applications, contributing to sustainable construction practices. Recommendations are provided for optimal mix design and future research on durability and long-term performance.
