Cement is being manufactured in many variants today. This
often confuses the layman who does not know which cement to use. Besides
Portland cement, the market offers blended or OPC cement as well. Technical
Data used in the field explained in drilling courses in Islamabad.
You would find many variants within Portland cement itself -
33, 43 and 53. Some manufacturers also produce cement varieties in forms such
as masonry cement, high strength cement and sulphated cement.
The important thing to remember is that there is no good or
bad cement, the choice should depend upon the intended application. It is
interesting to note that while in the earlier times, only Portland cement used
to be available, the abundant supply of fly ash resulted in the development of
Pozzolana cement. Some more details of drilling courses in
Islamabad are as under.
The demand from rail companies for high strength cement to
be used for manufacturing sleepers put a pressure on cement manufacturers to
produce special variants of cement. Such high grades of cement are also
required in the construction of long span bridges, high rise structures and
other structures of gigantic magnitude.
Broadly speaking: 33 Grade cement meets the
requirement of small constructions 43 Grade cement is used for
pre-cast concrete production and sleeper manufacture , o 53 Grade cement is
used for heavy infrastructure and civil engineering applications.
One important point that must be remembered is that for most
industrial and heavy applications, cement is not used directly but is rather an
important input for concrete. Blended varieties of cement provide higher levels
of strength and durability. TSK Training for Skills and Knowledge is the best
institute in Rawalpindi Islamabad for Pakistani Students who wants to join drilling courses in
Rawalpindi.
