What it is
Durability comes from a low water-cement ratio, the right cement, enough cover of concrete over the steel, good compaction and proper curing. Indian standards set these by how harsh the exposure is.
Key points
- Low water-cement ratio, so fewer pores
- Enough cover so the steel stays protected
- Good compaction with a vibrator, no honeycombs
- At least 7 to 14 days of curing
Why it matters
Near the coast, salty air speeds up rusting of the steel inside concrete. In Chennai, durable concrete is the difference between a house that lasts and one that spalls.
How Elamentt handles it
We specify concrete grade and cover to the structural drawings and keep curing on the daily site checklist.
