IDENTIFICATION STUDY AND MECHANICAL CHARACTERIZATION CLAY STABILIZED BY GUMARABICSEYAL

The construction of infrastructures contributes to the development of a country, in particularthat of sustainable, economic and ecological social housing. Chad, withitsdemographic boom, isfacingthishousing and energycrisis. This experimentalstudyaims to determine the mechanicalresistance by the compression simple of local construction materials. A geotechnicalstudy of the materialwas made, including the grain size, Atterberglimits, methylene blue and normal Proctor tests.The experimentalresults of the mechanical tests show that the mechanicalstrengthgoesfrom 3.17 MPa for 100% clay to 4.04 MPa for 8% of gumarabic. Fromthisresultitcanbeconfirmedthatgumarabiccanbeused as a stabilizer for clay-based building materials.
