2. normalizing (to produce a uniform, fine-grained micro-structure, by air cooling)
3. quenching (to harden, by rapid cooling)
4. tempering (to toughen, by reheating)
Purpose of Curing Concrete – – Control humidity and temperature of fresh concrete
– Prolong hydration of cement
– Reduce concrete internal void
– Protect concrete from extreme weather condition
– Protect concrete from vibration, impact and other disturbances during curing
