Cement is the most widely used construction material all over the world. It is important to choose the best cement available for construction of your house.
There are lots of brand available in the market which promise to give the best result. but first we will know about the type of cement used in the house construction.
There are two different types of cement generally used for residential house construction.
1. Ordinary Portland Cement (OPC)
2. Portland Pozzolana Cement (PPC)
1. Ordinary Portland Cement (OPC)
OPC is most widely used cement in construction industries.
It is made by the chemical combination of Calcium, Silicon, Aluminum, Iron and other ingredients in controlled conditions. Ordinary Portland Cement used for the construction purpose can be found in 3 different grades, They are
1 33 Grade
2 43 Grade
3 53 Grade
33 Grade Cement
It is used for small-scale constructions where the strength of concrete is not taken into account
43 Grade Cement
It is used for the medium-scale construction where medium strength is required
It is used majorly for wall plastering works, Non-RCC structures, Pathways etc. 43 grade cement attains a compressive strength of 43Mpa in 28 days of setting.
Make sure that your 43 grade cement brand adheres to IS 12269 standard code.
53 Grade Cement
It is used where a very high strength of concrete is required it is not used in house construction but can be used in special projects or mass constructions
It is mainly used in RCC and pre-stressed concrete of higher grades, cement grouts etc. 53 grade cement used for fast placed construction were the initial strength has to be achieved quickly.
Like wise 43 grade cement, 53 grade cement attains 53Mpa in 28 days
Make sure that 53 grade cement adheres to IS 8112 standard code.
Portland Pozzolana Cement (PPC)
PPC has now become the famous and used of PPC has been increasing nowadays in he construction industries, because of its pozzolanic material that imparts better properties to cement.
It is made by keeping the pozzolanic material as the main constituents. the percent age of pozzolanic material lies between 10 to 30 %
Unlike OPC, PPC does not come with different grade. though the strength of the PPC cement is comparable to OPC 53 Grade cement.
Advantages Of Using OPC
- It is cheaper than PPC and can be easily available anywhere
- Give performance in long term as compare to OPC
- Better resistance against chemicals
- Better workability
Choosing Between PPC and OPC
One thing you should keep in mind while choosing between PPC and OPC is how much time you want to keep scaffolding, because PPC has higher setting time where as OPC has lower setting time.
If you want to remove the scaffolding in less time then you should go with the OPC
Both type of cement are good for residual construction. the only factor that differ from each other while choosing in between them is setting time.
