Cement is the main component of concrete and a chief construction material used in construction projects worldwide. Cement is prepared by the mixture of limestone and clay which is ground together and then heated at a temperature of 1,450°C which results in a granular substance called clinker.
There are varieties of best cement for making home available in the market with different properties for different applications such as Ordinary Portland Cement, Portland Pozzolana Cement, Rapid Hardening Cement, Quick Setting Cement, Low Heat Cement, Sulphate Resisting Cement etc.
Both Ordinary Portland and Portland Pozzolana types of cement are widely used for construction purposes. OPC is produced by simply grinding limestone and secondary materials to a powder; and the Portland Pozzolana is a variation of ordinary Portland with added mixture of Pozzolanic materials like Fly ash, volcanic ash, clay, slag etc in the ratio of 15% to 35% by weight, which increases the strength of the concrete.
Both OPC and PPC are eco-friendly materials but Pozzolana Cement is made of natural and industrial waste. OPC is available in 3 grades such as grade 33, 43 and 53 and Pozzolana is available in only one grade and its strength is equal to the strength of grade 33 of OPC. PPC produces highly durable concrete as it has low water permeability compared to OPC. PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing. And PPC is cheaper also compared to OPC.
PPC is highly resistant to sulfate attacks and thus it has its applications in mass concrete work like dams, huge foundations, and building near seashore, reservoirs and in other marine works. OPC is highly applicable where the fast pace of construction is required. It cannot be used for mass concreting as it has a high heat of hydration.
Both the types of cement have its own advantages and applications-
Ordinary Portland Cement
- It has high initial setting strength.
- The manufacturing process is easy
- It does not possess resistance to sulfate attacks
- Cost is higher compared to PPC
- Has less durability and workability
Portland Pozzolana types of cement
- It has less initial setting strength but hardens over time
- The manufacturing process is difficult
- It can resist sulfate attacks
- Has better durability and workability
- Cost is less compared to OPC
These are the best cement for making home.
