There are four major compounds in cement and these are
known as C2S, C3S, C3A & C4AF, and their composition varies
from cement to cement and plant to plant.
In addition to the above, there are other minor compounds
such as MgO, TiO2, Mn2O3, K20 and N2O. They are in small
quantity. Of these K2O and Na2O are found to react with
some aggregates and the reaction is known as Alkali Silica
Reaction (ASR) and causes disintegration in concrete at a
later date.
The silicates C3S and C2S are the most important compounds
and are mainly responsible for the strength of the cement
paste. They constitute the bulk of the composition. C3A and
C4AF do not contribute much to the strength., but in the
manufacturing process they facilitate combination of lime
and silica, and act as a flux. In a typical Portland
cement, the composition of mineralogical compounds could be
