What it is
Cement sets and hardens by a chemical reaction with water called hydration. The main types used in homes are OPC (ordinary Portland cement), PPC (Portland pozzolana cement) and PSC (Portland slag cement), plus white cement for finishing.
Types and key points
- OPC: fast strength gain
- PPC: made with fly ash, slower and more durable
- PSC: made with slag, good against salts
- Sold in 50 kg bags; use within about three months
Why it matters
Old or damp cement loses strength. Check the manufacturing date on the bag.
