Solution:
  • Curing is the process of maintaining satisfactory temperature and moisture conditions in concrete long enough for hydration to develop the desired concrete properties.
  • The potential strength and durability of concrete will be fully developed only if concrete is properly cured.
  • For concrete exposed to dry conditions, the minimum curing period is 10 days.
  • It is recommended that above minimum periods may be extended to 14 days where mineral admixtures or blended cements are used in the concrete.
