Concrete cures through a process called hydration. To cure properly it has to 1) not freeze and 2) not have the moisture in it evaporate too quickly. Either case will weaken the concrete. Hydration usually takes 28 days at which point the concrete has reached 90% of its cure strength.

In many areas, especially out west (Low Humidity), they will actually soak the slab for several days with water. This stops the hydration from occurring too quickly, and keeps the strength of the concrete at it's highest.

Soaking is pretty common in Ohio also. Not so in Tennesse?

I ve put up structures all over the country and I ve used water and burlap sacks but with the advent of soft saws allowing us to get on the slab while it is real green, reducing spalling. The wonders of science with all theses Cure-n_Seal products, that unless it's a small pour, 10,000 sq ft or less would not expect to see the old sprinklers and burlap.

Nowadays at least in the Ohio area, the concrete is sealed soon after finishing, this slows the hydration without having to use burlap or keeping it damp with the hose.
