Quick Answer: What Happens If Wet Concrete Freezes? -
2021-6-30 Concrete can successfully placed, finished, and cured in cold weather or during the winter, but it requires an understanding of the impact of cold weather on the process of creating long-lasting concrete. Fresh and newly-hardened concrete both lose moisture and heat rapidly in cold-weather conditions. Can you pour concrete if it freezes at night?

What happens if concrete freezes before it sets?
Concrete sets much slower in cold weather. In order for hydration to occur, the temperature of the concrete must be ≥ 40ºF. It is critical that the concrete sets before it is exposed to freezing temperatures. The problem is when all of the water freezes; it expands, causing your concrete to crack.

Cold Weather Concrete- What happens to fresh concrete
Significant overall reductions in strength gain, up to 50%, can occur if concrete is frozen before it reaches 500 psi. Concrete that goes through just one freeze cycle before reaching 500 psi may be restored to nearly normal strength if proper insulating/curing

New Concrete Foundation or Slab Freeze Damage
Concrete surface flaking - is a most common visible sign of inadequate cold-weather protection of concrete during a pour. If the surface of the new pour freezes, flakes of water/concrete may pop off; if the flaking is severe, repair or replacement may be needed. If flaking is trivial/superficial only, then this is probably only a cosmetic item.

Problem With Frozen Concrete During Curing eHow
2021-8-5 When the water trapped in freshly poured concrete freezes, it drastically lowers the finished strength and durability of the slab. Strength drops by up to 50 percent, according to the National Ready Mixed Concrete Association. The curing process allows concrete to bond tightly together through the formation of crystal structures.

What happens to Concrete when it freezes? Total Concrete
Concrete must be protected from freezing until it reaches a compressive strength of 500 psi. This usually occurs within the first 24 hours. Water expands 9% in volume when it freezes. The formation of ice crystals in the concrete will cause paste expansion that reduces the final strength of the concrete
