Abstract

Three brands of Portland cement products (CEM A, CEM B and CEM C) available in Ghana have been studied for their chemical oxide compositions (CaO, SiO2, Al2O3, Fe2O3, SO3 and MgO). The oxide concentrations were determined using energy dispersive X-ray fluorescence (EDXRF) spectrometry. The validity of the EDXRF method was checked by analysis of NIST SRM 1889a (Portland cement). Excellent agreement between measured results and certified values confirms the reliability of the EDXRF method used. The major compounds (C3S, C2S, C3A and C4AF) and control ratios (LSF, SR and AR) were also assessed for quality of the cement products and the results obtained compared with the European standard (EN 197-1) specification. The results obtained for all the analysis showed that CEM A and CEM B cement conforms well to the European (EN 197-1) standard specification except CEM C cement which did not conform to the standard specification.
