Cements used for domestic building like your home ar primarily of 3 types:
Ordinary Portland cement (OPC): a mix of clinker and mineral.
Portland scum Cement (PSC): a mix of excellent quality furnace scum (from the iron and steel industry) with clinker (which makes OPC) and mineral.
Portland Pozzolana Cement (PPC): a mix of fly-ash (from thermal power plants) with clinker and mineral.
Ideal cement for house construction:
The best cement for house construction is mixed cement like PSC and PPC. however please note that sensible quality integrated cements like PSC and PPC can take longer to line. but the ultimate strength once twenty eight days are far more.
- Features of excellent quality cement:
- Reduced water demand.
- Improved workability .
- Less leaky to wet.
- Improved resistance to acids and chlorides.
- Reduced heat of association.
- Easier to end.
- Reduced shrinkage.
- Reduced natural action issues as a result of it's low on free lime.
The colour of cement has no regard to the strength characteristics. there's a wrong impression that darker color cement offers higher strength. In fact, darker color cement causes the staff to feature a lot of sand than allowed in cement-sand mortar for daubing, which may then cause issues.
Selecting the correct cement for your house :

Remember, that by exploitation thirty to forty luggage less of cement, you'd save no over Rs 3000 to Rs 4000.
