Abstract:
This study was conducted to determine the main elements contents of clay samples collected from
different parts of Sudan (Omdurman, Marawi, Blue Nile, Kosti, Umm Ali and Portland cement) using
gravimetric and volumetric techniques as classical chemical analysis and compare the results obtained
to the X-ray fluorescence as a physical method of analysis adopted recently. The results obtained from
chemical analysis were as follows: losses on ignition were in the range 1.06 to 24%; SiO2 were in the
range 20-70%; Al2O3 9-33%; Fe2O3 0.05-9.40%; MgO 2-10%; CaO 0.6-61.07; K2O, 0.1-3.6% and
Na2O 0.11-4%, depending upon the type of soil whether koalinite, montmorillonite or illite. The XRF
analyses showed some agreement to chemical analysis in a loss on ignition, Fe2O3, Al2O3 and CaO,
however, differ in K2O, Na2O, SiO2 and MgO.
Keywords: Sudan clay, analysis, Chemical, XRF.
