Pouring Concrete in Cold Weather: How Cold is Too Cold?
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.Even when daytime temperatures are within the satisfactory range, winter concrete setting creates risks that could result in weak, inadequate concrete.
