Concrete curing is a process in which the cement and the water
in concrete bond and harden through a chemical reaction called
hydration. As they bond, the cement and water bind the aggregate
and the sand to form a strong foundation structure. Proper
curing is critical to the strength and durability of concrete.
When a slab-on-grade foundation is curing, it's important to
provide enough time for hydration to take place. Hot, dry
conditions make water evaporate more quickly from the slab
surface, which can cause concrete to harden more quickly,
ultimately leading to a weaker material that's at greater risk
of curling and cracking. The surface of the slab must be kept
moist to prevent water from evaporating too quickly. Inadequate
hydration reduces the slab foundation's strength, durability,
impermeability, resistance to abrasion, and resistance to
freeze-thaw cycles. There are several ways to keep the slab
surface moist during the curing process. One method is to apply
curing blankets for a minimum of three day
