Curing of Concrete

When concrete has begun to harden after about two hours of laying, then it should be kept wet by covering with wet gunny bags or wet sand for 24 hours. It is called curing of concrete. Concrete is cured to complete the hydration process, and to gain strength of concrete.

After 24 hours, concrete is cured by:

  • making mud walls of 3 inch or 7.5 cm high.
  • covering with wet sand or earth and kept damp continuously for 15 days.
  • It can also be done by covering with special type of water proof paper so that water may not escape through evaporation.
