Submitted by: Muhammad

Curing is the process of maintaining the moisture and temperature conditions for freshly deployed concrete. This is done for small duration of time to allow the hardening of concrete. The methods that are involved in saving the shrinkage of the concrete includes:
☛ (a) Spraying of water: on walls, and columns can be cured by sprinkling water.
☛ (b) Wet covering of surface: can be cured by using the surface with wet gunny bags or straw
☛ (c) Ponding: the horizontal surfaces including the slab and floors can be cured by stagnating the water.
☛ (d) Steam curing: of pre-fabricated concrete units steam can be cured by passing it over the units that are under closed chambers. It allows faster curing process and results in faster recovery.
☛ (e) Application of curing compounds: compounds having calcium chloride can be applied on curing surface. This keeps the surface wet for a very long time.
