What it is
Admixtures can make concrete flow better with less water, set faster or slower, resist water, or trap tiny air bubbles. They are measured carefully, as a small percentage of the cement weight.
Types and key points
- Plasticisers: better flow with less water
- Retarders: slower setting in hot weather
- Accelerators: faster setting
- Integral waterproofing compounds
Why it matters
Used right, admixtures give stronger, denser concrete in Chennai's heat. Used wrong, they cause delays and weak spots.
How Elamentt handles it
Admixtures are used only as specified by the structural engineer or the ready-mix supplier.
