Determination of the Composition of Cement Raw Materials and Mixes

This study determine the composition of cement, raw materials and mixes. The range of parameters determine in percentage were as follows: SiO2 (0.7245-59.8512), Al2O3 (0.1915-18.0996), Fe2O3 (0.1326-33.1373) Cl (0.01), CaO (0.5231-56.7013), F/CaO (0.88), MgO (0-1.9301), K2O (0.2102-0.4580), IR (0.5-1.5), LOI (0.72-42.99), SO3 (0-1.6520), N2O (0.1058). All these components were determined in accordance with the Nigeria Industrial Standard and the result obtained compare well with British Standard (BS) specification and Nigeria Industrial Standard. It is important that the concentration (in percentages) do not exceed certain limits because below or above the limits will have disastrous effect on the cement and concentrate that will later be produced
