1. Uses and Advantages of Cement
The overwhelming majority of cement is utilized as a means of
makingconcrete as well as concrete products. The use and
manufacturing of cement products are two of the advantages of
cement, which is the most useful and valuable mineral in the world.
How are Cements Manufactured?
The manufacturing of cement involves a combination or raw materials,
normally approximately 85 percent limestone or rocks such as marl or
marble; the rest is primarily shale or clay. The mixture is then heated
until it almost melts and then it is ground out into powder form. It
takes approximately 1.7 tons of these raw materials to manufacture a
ton of cement and a cement calculator is sometimes used during the
process.
Process of Hydration
When water is added to cement, it turns it into a paste. Then the
paste is combined with other materials like rocks, gravel, sand and
other aggregates, the paste will binds them together and make a
tremendously tough product that is called concrete. The mix hardens
as a result of a chemical reaction that takes place between the mixed
parts. This reaction is known as hydration and during this process,
crystals will radiate outwards from the grains of the cement and
interlock with the other adjacent crystals or stick on to the
aggregates. By volume, the usual mixture to create concrete is
approximately 15 to 20 percent water, 60 to 75 percent aggregates

2. and 10 to 15 percent cement; the strength of the mixture is one of the
advantages of cement.
Main Kinds of Cement
For all useful purposes, the only kind of cement that is exercised in
modern construction is referred to as Hydraulic cement. The two major
kinds of cement are masonry cements and Portland cements. Portland
cement makes up in excess of 95 percent of the cement that is
manufactured in the United States; masonry cement which is utilized
for mortar and stucco accounts for the majority of the balance.
The inventor of the Portland cement is not known; however, Joseph
Aspdin patented it in 1824 in England. The cement was then
nicknamed as Portland cement because the color is almost the same
as that of the stones quarried on the Isle of Portland, which is off the
British coast to the south.
Approximately 75 percent of the cement that is produced is utilized in
the making of ready-mix concrete and it is utilized to build bridges,
buildings, walls, sidewalks, and all types of constructed structures.
