In this work, we study the effect of dune sand content on the compressive strength of a matrix soil of sand-clay-gypsum. The content of dune sand added to soil is: 2%, 4% and 6%. The samples prepared were kept in an oven for 24 hours at a temperature of 20 °C. The results obtained demonstrate that the mechanical resistance has a significant increase at 2% to 4% of dune of sand. But this mechanical resistance decrease at 6% of dune sand, the ideal percentage is 4% with a resistance of 3.54 MPa.
