2016-10-23  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.
