What it is
The pozzolana reacts slowly with the cement over months, filling pores. PPC gains early strength slower than OPC but becomes denser and more resistant to water and chemicals.
Key points
- Slower early strength
- Less heat while setting
- Better long-term durability
- Popular for plaster, masonry and many structural uses
Why it matters
Its density and resistance to moisture suit Chennai's humid, coastal climate.
How Elamentt handles it
We use PPC where the engineer specifies it; the type is written in your specification.
