ABSTRACT:
Geotechnical tests conducted on clayey materials of
Missole II, Douala sub-basin of Cameroon showed that these materials present:
fines particles (55 to 78 wt.%), sand (22 to 44 wt.%), and plasticity index of
13.8 to 21.6%. The X-ray diffraction (XRD) and the chemical analysis revealed a
kaolinite amount of 46 to 56 wt.%, 19 to 27 wt.% of illite, 12 to 19 wt.% of
quartz, 3 to 5 wt.% of goethite, 2 to 5 wt.% of hematite, 1.5 to 5 wt.% of
anatase, 2 to 3 wt.% of feldspar-K with 52.87 to 63.11 wt.% of SiO2,
18.08 to 24.31 wt.% of Al2O3, 3.28 to 11.45 wt.% of Fe2O3 and a small content of bases (
