    Chemical Composition of Cements

    Oct 23, 2016 Oct 23, 2016 A good cement should consist chiefly of SiO2 and CaO, with a little Al2O3 and Fe2O3, and less than 2% MgO, and 1.5% CO2 and SO3. From this the student will see that the accurate determination of MgO, CO2, and SO3 is a matter of much importance, and that in many cases the determination of these three items may be sufficient to decide the fate of the cement

In the chemical analysis of cement, its elemental composition is analyzed (e.g., Ca, Si, Al, Mg, Fe, Na, K, and S). Then, the composition is calculated in terms of their oxides and is generally expressed as wt.% of oxides
