OPC 53 grade cement

Types of Cement and their Uses

 

Ordinary Portland Concrete (OPC) is accessible in three distinct evaluations in India as 33 grade (IS: 269-1989), 43 grade (IS: 8112-1989) and 53 grade (IS: 12269-1987).
The numbers 33, 43 and 53 speaks to 28-day compressive quality of bond mortar as 33 MPa, 43 MPa and 53 MPa. The qualities are gotten from standard tests on bond sand mortar examples.
Every one of the evaluations are created from a similar fundamental material, however higher quality is accomplished by expanding the tricalcium silicate content and furthermore by better pounding of the clinker.
Indian Standard Code (IS: 456: 2000) grants the utilization of the accompanying Portland concrete for explicit sorts of work.

Ordinary Portland Concrete (OPC)

In Ordinary Portland Cement evaluations of 33, 43 and 53 are just allowed. These kinds of bond are most ordinarily utilized by and large solid development.

Rapid Hardening Portland Cement (RHPC)

This bond is like OPC, in which the level of Tricalcium silicate is more, and less Dicalcium silicate and ground all the more finely. It has the nature of accomplishing high quality in a brief timeframe and favored for development purposes where speed is of significance.

Portland Slag Cement (PSC)

This concrete is made by between crushing Portland Cement clinker and granulated impact heater slag. This concrete has high protection from sulfates, and it is reasonable for situations presented to sulfates.


Portland Pozzolana Cement (PPC)

The pozzolanic materials utilized in assembling are Fly fiery debris and Calcinated mud. These concretes respond with water because of the nearness of calcium hydroxide freed in the hydration procedure. It picks up quality moderately gradually and subsequently needs all the more relieving time. Because of this, this bond is favored where time isn’t of significance like in mass cementing.

Hydrophobic Portland Cement (HPC)

Hydrophobic is the water-repellent property of the material. This bond is produced by between pounding Portland concrete with 0.1-0.4% of oleic corrosive and stearic corrosive. This bond has a hydrophobic quality which encourages its stockpiling for longer periods in amazingly wet climatic conditions.

Low Heat Portland Cement (LHPC)

This concrete contains low characteristics of tricalcium aluminate and high characteristics of dicalcium silicate. The hydration procedure is moderate contrasted with PPC and is alluring for mass cementing purposes like gravity dams. As it has moderate quality addition, care ought to be taken while evacuating the formwork early.

Sulfate-opposing Portland Cement (SRPC)

This concrete contains about 5% of tricalcium aluminate and is ground better than OPC. This bond is very sulfate safe and is utilized in areas where sulfates are available in the environment or soil.

Different Types in Cement

High Alumina Cement

This concrete is acquired by crushing high alumina clinker and has a long introductory setting time, high extreme quality, high protection from the activity of acids and high temperature. This bond is utilized for exceptional structures that require impenetrability and erosion opposition like in heater protection, recalcitrant cement.

Stone work Cement

This concrete is gotten by between pounding a blend of Portland Cement clinker with non-pozzolanic materials, gypsum and air entraining plasticizer. It contains some physical properties like moderate solidifying, high functionality and high water retentivity, which turns out to be truly reasonable for brick work.

Oil-well Cement

It is water driven concrete which contains retarders notwithstanding coarser crushing and is reasonable for high weight and temperature.


Speedy setting Cement

This bond is exceptionally made for submerged cementing. It is gotten by including a specific amount of aluminum sulfate and lessening the amount of gypsum and made into a fine powder.

Extending Cement

This sort of concrete is created by including an extending medium like sulpho-aluminate and a settling operator to customary bond. This bond is utilized for fixing solid surfaces as it grows amid relieving.

Acid-resistant Cement

It is utilized in the compound business as it has corrosive safe quality, which is acquired by including materials like quartz, sodium silicate and sodium fluosilicate to the bond.

White Cement

This bond is scorched by oil and does not contain shading specialists, for example, iron oxide, manganese oxide or chromium oxide. This bond is utilized for floor get done with, putting, pointing of brick work, assembling of precast stones, tiles, runaway markings and shading concrete.


Coloured Cement

At first blending shading materials can give the ideal shading to concrete. It is utilized for outside completing of dividers and floors, assembling of tiles and precast stones, garden ways, pools and tennis courts.
