-The objective of our study is the physico-mechanical characterization of quarry sands in the West Cameroon region with a view to their rational use in civil engineering works. This work was done in two ways: • In the field we took samples • In the laboratory we did some tests. Laboratory studies focused on: ✓ Physical characterization which is an intrinsic property: water content, specific weights, density, sand equivalent, dry particle size analysis, sedimentation, granularity. ✓ Mechanical characterization: Proctor test, CBR test and concrete formulation. The study concludes that representative samples of the sand analyzed have physical and mechanical properties such that: the specific gravity is 2.46 g / cm3, the apparent density is 1.9 g / cm3, the sand equivalent is 67.2 %, The modulus of fineness (Mf) is 3.3, The Immediate CBR is 10.37, the Normal Proctor test shows a maximum dry density of 1.68g / cm3 for an optimal Moisture content of 12.18 %, the Modified Proctor test also stands out a maximum dry density of 1.74 g / cm3 for an optimal Moisture content of 14.8 and the compressive strength of Concrete at 28 days is 25.08 MPa.
