The present study deals with the distribution of major oxides (Al2O3, CaO, Fe2O3, SiO2 wt%), minor oxides (Cl, K2O, MgO, MnO, Na2O, P2O5, TiO2 wt%), trace elements (Co, Cr, Cu, Ni, Zn ppm.) and the consituents of free lime, insoluble residue and loss on ignition in (38) representing different types of portland cement produced at ( 13) Iraqi factories during the interval 1997 / 1998. The study is concerned with variation in the chemical composition in relation to the nature of raw material or raw mix, burning, cooling and storing conditions and the content of major phases in ordinary, sulfate resistance and white portland cement.
