Does wetting concrete make it stronger
ANSWER: Keeping concrete moist helps the curing process.
Concrete hardens as a result of a chemical reaction, called hydration, between cement and water, not because it dries.
Moist-curing concrete for 20 days more than doubles its strength compared to four days of moist-curing, which is considered a minimum..

Will concrete set if it’s too wet
When a concrete mixture is too wet, it causes a greater amount of shrinkage during the drying process than is needed. As a result, the concrete has a great likelihood of cracking and for those cracks are likely to be a fairly good size. … A watery mix actively reduces the compressive strength of the dried concrete.

What happens if you add too much water to mortar
Mortar that is too wet will run out between the joints. If it is too dry, the bond will be weak. Mound the mix and form a depression in the center.
How long does concrete take to harden
After 7 days, the concrete will have gained around three quarters of its compressive strength, but you should refrain from driving vehicles or heavy machinery over the surface until after the 28 day mark. For domestic mixes – driveways, for example – you can expect the concrete to be set within 24-48 hours.
How long does quikrete need to set before rain
about 2-4 hoursIf the rain occurs when the concrete is fresh (about 2-4 hours after mixing), the surface should be protected from the rain. If the finishing process was recently completed, rainwater may not cause damage as long as it is not worked into the surface and the slab is left untouched.
