Abstract

This work concerns the geotechnical and mechanical studies of the soils of two sites located in the locality of Djarmaya located 5 km from the oil refinery. First, these two sites were located and then a site raid was carried out. The experimental devices used as well as certain physical and mechanical parameters were studied. Finally, the geotechnical characterizations of two soils focused on the particle size analysis by sieving and sedimentometry, the Atterberg boundaries, and the density of the solid grains. We observe that there is a similarity between the results obtained. However, the first sample consists of two samples have almost the same amount of silt, but there is a slight difference in terms of sand and clay. However, the results showed us that the soils are clayey and not very plastic. This result shows that flexural and compressive strengths vary with increasing cow dung. When the percentage of cow dung increases from 0 to 4%, the flexural strength also decreases from 0.79MPa to 1.15MPa. Similarly, compressive strength increases from 1.98 MPa to 2.25 MPa when the percentage of cow dung increases from 0% to 4%. This variation in flexural strength is explained by the behaviour of cow dung due to the fact that it is a lightweight material and by the mode of failure. During drying, the specimens did not shrink. In addition to the geotechnical test, a mechanical characterization study of the latter showed that the soils were suitable for construction.
