Which type of cement is best for house construction in India?
For most homes, PPC (Portland Pozzolana Cement) is preferred due to its long-term durability, especially in damp climates, while OPC (Ordinary Portland Cement) is used when early strength is needed.

How do I check the quality or freshness of cement before buying?
Check the manufacturing date on the bag—cement should be used within 3 months of manufacture. Good cement feels smooth when rubbed, is uniform in color, and sinks in water without floating.

What are the differences between OPC and PPC cement; which should I choose?
OPC gives quick strength and is good for urgent construction needs, whereas PPC sets slower but is more durable and resistant to harsh weather and chemicals.

Can I use one type of cement for the whole house?
Usually, PPC can be used for most parts of a house, but some areas like foundations or heavy load-bearing sections may benefit from OPC for faster strength gain.

How does the choice of cement affect durability, weather, and moisture?
PPC resists moisture and weathering better, making it ideal for bathrooms, roofs, and coastal regions, while OPC is suitable for quick construction in dry areas.

Is it safe to use cement from local brands, or only major brands?
Always buy from ISI-marked, BIS-certified brands—well-known or reputed local brands are fine if they have these certifications and proper packaging.

What is the cost difference between major and local cement brands; does it reflect quality?
Major brands may cost more but often guarantee consistent quality; some local brands are good but always check for certifications before purchasing.

How long can cement be stored, and how should it be stored?
Cement should ideally be used within 3 months of manufacturing and kept in a dry, raised area with plastic sheets to avoid contact with moisture.

What is the correct water-cement ratio for home construction?
The general ratio is about 0.4–0.6 parts water by weight to 1 part cement, but follow your engineer’s or manufacturer’s recommendation for best results.

What approvals, IS codes, or accreditations should I check when buying cement?
Look for the ISI mark and check that the cement conforms to relevant IS codes (like IS 269 for OPC-33, IS 1489 for PPC) to ensure safety and compliance.

What mistakes should be avoided when using cement during construction?
Don’t use old or lumpy cement, avoid mixing with too much water, always cure freshly laid cement, and keep it covered from moisture until used.
