Different Types of cement – 17 Types

Cement is the one of the essential binding material in construction and we knew the importance of cement in construction. So many types of cement have manufactured and we have to decide the right cement for the construction.

So in this post, we are going to discuss the different types of cement and its uses.

Different grades of cement

Types of Cement

  1. Natural Cement
  2. Artificial Cement

Natural Cement

Natural Cement is manufactured from crushed stone which is having 20 to 40% of clay content and remaining lime mixed carbonate magnesia.

It holds brown colour and sets rapidly when mixed with water.

Artificial Cement

Artificial cement is produced by the composition of the different material. The Artificial cement is classified below.

Ordinary Portland Cement

Ordinary Portland cement is widely used to construct normal structure where the special cement properties are not required. It produces the medium range of strength development and heat generation.

OPC cement is resisting the dry shrinkage and cracking but it has less resistance to chemical attack.

Different grades of OPC cement is availabel in market.

Modified Portland Cement

Modified Portland cement is developing less heat of hydration compared to OPC cement. Mostly these type of cement is used in hot climate location.

Rapid Hardening Portland Cement

Rapid hardening cement is also known as “High early strength cement” because it produces the strength at the age of 3 days is equal to the 7 days strength of OPC cement with the same water-cement ratio.

A higher percentage of CS (Tricalcium silicate) has added into the cement to attains the higher strength in short period and also it is lighter than OPC.

This cement attains the higher strength in short period so we can remove the formwork in an earlier period.

Extra Rapid Hardening Cement

This cement has manufactured by adding 3% of calcium chloride with Rapid Hardening Portland Cement.

Extra rapid hardening cement is preferable to use when high strength required in a very short period. It gives 25% higher strength than RHP Cement in 2 days and 10 to 20% higher at 7 Days.

Low Heat Portland Cement

Low heat cement is mainly used in mass concrete (Raft Concrete) work because it produces less heat of hydration.

It contains a low percentage (5%) of CS and a high percentage (46%) of CS and remaining materials are same as ordinary cement.

Due to its less compressive strength, it is not suitable to construct the structure.

C3 S – Hydrate Quickly          CS– Hydrate Slowly

Sulphate Resisting Cement

This cement is used to where sulphate impact action is high. The Tricalcium Aluminate (CA) increase its resisting capacity against sulphate.

It is expensive and not easily available because a special raw material has required for manufacturing the cement.

Water-proof Cement

The water-proof cement is manufactured by adding waterproof additives and some metal like Ca, Al with ordinary or RHC cement.

Waterproof cement is used to construct the water retaining structure like dams, tanks.

High Alumina Cement

High Alumina cement has manufactured from bauxite and limestone and it attains the high strength in short period. Its achieve the strength after 1 day up to 40 Mpa.

High alumina cement is used for the construction of underwater-related works because of its good resistant capacity against sulphate.

Quick Setting Cement

Quick setting cement contains less percentage of gypsum and Aluminium Sulphate. The setting time of this cement was accelerating by Aluminium Sulphate.

Initial Setting Time – 5 Minutes and Final setting time – 30 Minutes

Quick Setting cement is used in the construction of the water retaining structure.

Slag Cement

Slag cement has manufactured by mixing of Portland cement and blast furnace slag. The price of slag cement is lower than the OPC cement. It is not suitable for normal RCC structure because it having less early strength.

Generally, slag cement is used in seawater construction because of its good sulphate resistance capacity.

White Cement

Mostly the white cement is used in architectural work because of its good aesthetic values. It was manufactured by the raw material iron oxide and manganese oxide adding with OPC.

Acid Resistant Cement

Acid resistant cement is manufactured by mixing of acid resistant aggregates like quartz and sodium fluosilicate with normal cement.

ARC cement is widely used in chemical industry.

Coloured Cement

Coloured cement is manufactured by adding 5 to 15% of suitable pigment while grinding the cement.

Example

Iron Oxide – Red colour

Chromium Oxide – Green Colour

Cobalt Oxide – Blue Colour

Expanding Cement

To produce the Expanding cement, the expanding material added with normal cement.

It is used in the construction of water storage structure.

Portland Pozzolana Cement

Pozzolana is a natural or artificial material having silica and alumina. It is having the good tensile strength and also economically good.

Mostly PPC cement is used in the construction of sewage works.

Super sulphate Cement

The super sulphate cement has manufactured by the combination of granulated slag, calcium sulphate and portland cement.

It produces less heat of hydration during the setting time.

Super sulphate cement is used in the construction of seawater related works.

Masonry Cement

This cement has manufactured by the raw material of Portland cement, gypsum and limestone. Normally its compressive strength is 2.5Mpa in 7 days.

IS Code for Cement

We listed out the IS code for cement.

Hope that we have discussed all different types of cement. Anything we missed to mention above post don’t forget to comment.
