Best Answer

This type of Cement is manufactured in form of different grades, the most common in India

being Grade-53, Grade-43, and Grade-33. OPC is manufactured by burning siliceous materials

like limestone at 1400 degree Celsius and thereafter grinding it with gypsum.

OPC gives enough comprehensive strength after soaking in water for 3 days, 7 days and 28

days. This is suitable for all types of modern civil engineering construction.

Limestone powder is the main ingredient, followed by clay and gypsum. There are lesser ingredients that make the cement behave better when mixed with water.

What is sulphur concrete?

Ordinary portland cement based concrete consists of a mixture of aggregates bound together with portland cement. In the presence of water a chemical reaction takes place and the portland cement is hydolysed. At the end of this chemical reaction the cement becomes hard and binds the aggregate particles together.Sulphur concrete is composed of a similar mixture of aggregates, however, and this is the big difference, there is no portland cement involved. Instead the aggregate mixture is bound together by molten sulphur at elevated temperatures. Upon placing, the sulphur concrete is allowed to cool and as it cools the molten sulphur becomes a solid again binding the aggregates together imparting rigidity to the concrete mix.Because sulphur concrete contains no alkaline materials, unlike portland cement mixtures, it is very much more resistant to acid attack and thus finds favour in industry where acid resistant concrete is desirable.


What is the difference between white cement and plaster of Paris?

There are only slight chemical and physical differences between gray portland cement and white portland cement. These differences are due to raw material differences and sometimes, though not always, slight differences in manufacturing. The goal is to minimize the oxides (particularly iron and manganese) that impart the grayish color normally associated with portland cement. Souce:PCA (portland Cement Association)


What are the chemical compositions of white cement?

The chemical composition of cement is Calcium oxide, Silicon dioxide, Aluminum oxide, Iron oxide, water, and sulfate. They mix, crush, and blend together limestone, silica (sand and other materials), aluminum, iron, and gypsum.


Is cement homogeneous?

Yes. The cement used to make concrete usually has sand, aggregate and Portland cement in it. That would make it heterogeneous.
