Hydration and hardening of concrete through the first a few days is important. Abnormally quick drying and shrinkage because of things for instance evaporation from wind in the course of placement may bring about improved tensile stresses at any given time when it has not still received sufficient toughness, causing larger shrinkage cracking. The early power of the concrete is often enhanced whether it is retained moist throughout the curing process.
