The need to build, the current cost of construction and the shortage of materials are contributing to the development of a building materials industry based on the use of industrial waste such as bauxite residues. This study aims to deepen knowledge on the use of bauxite dust from the Compagnie des Bauxites de Guinée (CBG) in the construction industry, with a view to recycling bauxite residues. The initial raw samples were characterised using X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), infrared spectroscopy (IR), thermogravimetric analysis and differential thermal analysis (TGA/TDA). The samples of bauxite residue mixed with sand and cement were formulated at RB80%-S10%-C10%, RB70%-S15%-C15%, RB60%-S20-C20%, RB50%-S25%-C25%. They were dried naturally for 28 days. The results obtained for various characterisation analyses, such as compressive strength, are 1.680 MPa. Compressive strength generally increases with drying time. These results are compared with the literature and present the potential for the ecological application of bauxite residues in low-cost building materials.
