Curing
- Start curing immediately after the concrete has hardened slightly and do it continuously.
- Sprinkle water on freshly-laid concrete surfaces until they harden slightly.
- Covered concrete surfaces like columns, sloping roofs, etc. with wet gunny bags, burlaps or straw, and ensure continuous wetness.
- For flat concrete surfaces like slabs and pavement, construct small bunds with lean mortar or clay. Fill it with water.
- Always maintain a water depth of 50 millimetres until the curing process is completed.
- Use water that is fit for drinking during the curing process.
- Cure the concrete for a minimum of 10 days in normal weather conditions.
- During hot weather (greater than 40°C), cure the concrete for a minimum of 14 days.
