Cement is the widely used construction material all over the world for the house construction. Choosing the best cement for house construction is necessary.
There are two types of cement generally used for general purpose house construction:
Different Grades of Cement used in Building Construction
OPC is generally available in three grades namely 33, 43 and 53 grades.
PPC is only available in 33 grade
What is Ordinary Portland Cement?
OPC is the most common type of cement which is used in house construction. It is made by chemical combination of calcium, silicon, aluminium, iron and other ingredients in controlled conditions.
33-grade cement is used for small-scale constructions where the strength of concrete is not taken into account i.e. small house construction.
43-grade cement is used for medium-scale construction where medium strength is required and concrete has to take loads of structure above it i.e. 3-floor house.
53-grade cement 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.
Advantages of OPC:-
i) Famous at all the regions in India for House Construction.
ii) It is available everywhere
iii) It attains early strength in less time
iv) It is available in different grades
v) Manufacturing Process is easy
Disadvantages of OPC:-
i) It cannot resist sulfate attack
ii) Its cost is higher
iii) It releases more heat
iv) It has less durability
v) Its workability is lower
What is Portland Pozzolana Cement?
Use of PPC is increasing nowadays in houses construction as it contains Pozzolana materials as its constituents which impart better properties to the cement.
Pozzolanic materials are the main constituents in the manufacturing of PPC. The percentage of pozzolanic material should lie between 10 to 30%.
It is ideal for use in the house construction due to fact that it gives better performance in the long term when compared to OPC.
Advantages of using PPC:-
i) It can resist sulfate attack up to some extent
ii) Its cost is lower
iii) It releases less heat
iv) It has better durability
v) It has better workability
Disadvantages of using PPC:-
i) Not famous in all the regions of India
ii) PPC is not available everywhere
iii) The manufacturing process is difficult
iv) It is available in one grade only
v) It attains early strength in more time
Conclusion: Which is the Best Cement for House Construction?
If one wants durability and workability, then I will advise the use of PPC. However, if you want to achieve early strength in less time so that you can remove the formwork as early as possible then I recommend you using OPC for house construction.
