In much of Rajasthan, summer temperatures cross 40°C and the air is dry and windy. Fresh concrete loses water fast, sets quickly and can crack before it gains strength. A few simple practices prevent most of the damage.
Plan the pour
- Pour early in the morning or in the evening, not at midday.
- Keep aggregates shaded and sprinkle them with water; use cool water for mixing.
- With RMC, ask the plant about retarding admixtures and the travel time to your site.
- Have enough workers, vibrators and finishing tools so the pour does not stop midway.
Protect and cure
- Start curing as soon as the surface can take it without damage.
- Use wet hessian, ponding on slabs, or curing compounds as advised by your engineer.
- Keep curing continuous; letting concrete dry and wet again causes cracks.
- Cure for at least 7 days for OPC and longer for PPC or blended cements, as specified.
Plaster and masonry
- Wet bricks before laying (AAC blocks need only light wetting).
- Cure plaster for at least 7 days; shade external walls in strong sun where possible.
Tip:Most hairline cracks in Rajasthan buildings come from poor curing, not poor cement.
Frequently asked questions
How long should a slab be cured?
Typically at least 7 days for OPC concrete and 10 days or more for PPC, longer in hot, dry weather. Follow your engineer's specification.
Do curing compounds replace water curing?
Curing compounds form a film that keeps moisture in and are useful where water is scarce. Apply them correctly and at the right time.
