To produce a good quality of concrete, both in respect of strength and durability, a properly placed well-proportioned mix must receive curing during initial stage of hydration under suitable environment. The term environment is important as temperature, relative humidity and wind velocity is the vital factor in this process.
What is curing?
The procedure taken for promotion of hydration of cementitious materials is called curing. The tasks consist of control on movement of moisture and temperature from concrete to environment and as well from environment to concrete. In brief curing can be defined as maintaining warm and moist environment around or into concrete just after placement to continue hydration of cement particles until the expected properties of concrete
