| Abstract | ||
| Raw materials which used in the industry of ordinary Portland cement produced at Kufa cement plants were studied chemically & mineralogically. Chemical analysis of six limestone samples selected from Euphrates formation at Bahr Al-Najaf area shows an increases in the concentration of CaO in some samples and an increases in MgO concentration in other samples. Clay samples have high concentration of SiO2 in comparison with Al2O3, Fe2O3, SO3 concentrations. Calcite is the dominant mineral in most limestone samples, while dolomite is the dominant mineral in other samples. Illite-montmorillonite, montmorillonite, kaolinite, chlorite and palygorskite are most important clay minerals recognized in clays associated quartz and calcite. Chemical and mineralogical analysis of raw materials shows their suitability for cement industry, most of oxides in the raw mix materials at Kufa cement plants meet the international specifications needed for cement production. | ||
