What is the normal temperature of concrete?
Typical specifications call for concrete placement temperatures between 10°C and 32°C. However, depending on the size of the element and the environmental conditions, different limit values are specified (ACI 301, 207).
At what temperature should the concrete be?
Temperature ranges for pouring concrete
Experts agree that the best temperature to pour concrete is between 40° and 60°F. When the temperature drops below 40°F, the chemical reactions that strengthen concrete slow down and can lead to a reduction in concrete strength.
What is the minimum and maximum temperature of the concrete?
Typically, the concrete temperature is limited to 70°C (160°F) during hydration. Also, what temperature is too cold for concrete? Experts agree that the best temperature for pouring concrete is 5060°F.
What is the maximum temperature for pouring concrete?
Experts agree that the best temperature for pouring concrete is 5060°F. The necessary chemical reactions that set and strengthen concrete are dramatically reduced below 50°F and virtually non-existent below 40°F.
What is the minimum temperature of the concrete?
Fresh concrete must be protected from frost, so fresh concrete must be protected as soon as possible. The temperature of the concrete upon delivery must not fall below 5ºC.

What temperature is too low for concrete?
Experts agree that the best temperature to pour concrete is between 40° and 60°F. When the temperature drops below 40°F, the chemical reactions that strengthen concrete slow down and can lead to a reduction in concrete strength.
What is the lowest temperature for concrete hardening?
Hydration is a chemical reaction in which the base compounds of the cement form chemical bonds with water molecules and become hydrates or hydration products. At temperatures below 27 degrees, the formation of ice on hardening concrete can lead to a violation of the integrity of the concrete due to cracking.
Can concrete harden in the cold?
There are two main problems with concrete pouring in the cold winter: the concrete can freeze before it has gained strength, which will destroy the matrix. Concrete cures more slowly when cold: very slowly below 50°F, below 40°F the hydration reaction almost stops and the concrete gains no strength.
Does concrete harden at 2 degrees?
All surfaces in contact with freshly poured concrete must be at least 2 degrees Celsius, but there are no temperature limits for reinforcement, just that they are free of ice and snow.
