At what temperature will concrete freeze?
In its plastic state, concrete will freeze if its temperature falls below about 25°F [-4°C]. If plastic concrete freezes, its potential strength can be reduced by more than 50% and its durability will be adversely affected.Click to see full answer.

In its plastic state, concrete will freeze if its temperature falls below about 25°F [-4°C]. If plastic concrete freezes, its potential strength can be reduced by more than 50% and its durability will be adversely affected.Click to see full answer. Likewise, people ask, what temperature is too cold for concrete?Experts agree that the best temperature to pour concrete is between 50-60 °F. The necessary chemical reactions that set and strengthen concrete slow significantly below 50 °F and are almost non-existent below 40 °F.Additionally, will concrete cure at 40 degrees? For high-early strength concrete that won’t be exposed to freeze-thaw cycles, one day at temperatures above 40 degrees is sufficient. But a concrete foundation or other structure that will carry high loads at an early age requires 20 days or more at a minimum temperature of 50 degrees. Also to know is, can concrete cure in freezing temperatures? If the concrete is kept at around 50°F, protection can typically be removed after two days. Cure concrete in cold weather without additional water; adding water will keep the concrete saturated so that freezing will damage it even after it reaches 500 psi compressive strength.How soon can concrete freeze?At specified curing temperatures, well-portioned concrete mixtures should attain this strength within 24 to 48 hours. Therefore, it is critical that newly placed concrete be protected from freezing for the first 24 to 48 hours or until the concrete attains a strength of approximately 500 psi.
