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:
Ordinary Portland Cement
It is the most common type of cement which is used in house construction. OPC is first in the race of best cement for house construction. It is made by chemical combination of calcium, silicon, aluminum, iron and other ingredients in controlled conditions.
OPC is available generally three grades namely 33, 43 and 53 grades. 33 grade is used for small-scale constructions where the strength of concrete is not taken into account i.e. small house construction.
43 grade 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 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 using OPC:-
i) It is widely used everywhere
ii) It is available everywhere
iii) It attains early strength in less time
iv) It is available in different grades
v) It can be manufactured easily
Disadvantages of using 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
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. It is second in the race of best cement for house construction.
It is made by using pozzolanic materials as one of the main constituents. The percentage of pozzolanic material should lie between 10 to 30%.
However, PPC is only available in 33 grade. 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) It is not widely used everywhere
ii) It is not available everywhere
iii) Manufacturing process is difficult
iv) It is available in one grade only
v) It attains early strength in more time
For choosing the winner of the best cement for house construction depends on the requirements of user, if one wants durability and workability, then I will advise use of PPC and it becomes the winner of the best cement for house construction.
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 and it becomes the winner of best cement for house construction.
