What Temperature is Too Cold to Pour Concrete?

Feb 03, 2021  The ideal temperature range for pouring concrete is 40 to 60 degrees over a 24-hour period. Between 40 and 60 allows the water to slowly evaporate from the concrete but is not cold enough to slow down the chemical process of curing.

Pouring Concrete in Cold Weather: How Cold is Too Cold?

Jan 07, 2021  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.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material in ARC-32. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined.
