Lateritic soils vary significantly in their characteristics, depending on the laterisation process they have undergone. Due to this diversity, physicochemical and mechanical tests may be necessary to assess the feasibility of using laterite soil. This research aimed to carry out compaction tests on laterite soil with the incorporation of iron ore tailings sediment (IOTS), sand and cement to assess the mixture that would produce suitable results for rammed earth. It was concluded that sand and cement made a positive contribution to reducing the optimum compaction moisture and increasing the dry apparent specific mass in mixtures without IOTS, but in mixtures with IOTS, cement and sand did not have a significant influence.
