What is the minimum and maximum temperature of concrete?
|Least dimensions of sections, cm||Minimum temperature of concrete as placed and maintained during the protection period, °C|
|Less than 30.48||12.77|
|30.48 to less than 91.44||10|
|91.44 to less than 182.88||7.22|
|Greater than 182.88||4.44|
Likewise, what is the minimum temperature of concrete?
Generally, a 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 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.
In this way, what is the maximum temperature of concrete?
Q.: Some concrete specifications contain a maximum temperature for the freshly mixed concrete as delivered. Typical values are between 80° and 95° F as measured by ASTM C 1064-86.
How do you calculate the temperature of concrete?
The formulas used to determine concrete temperatures are shown below:
- Cold Weather. T = [0.22(TsWs + TaWa + TcWc) + TwWw]
- Hot Weather. T = [0.22(TsWs + TaWa + TcWc) + TwWw ¡
- Transportation Temperature Factors. For revolving drum mixers.
- A better way.

- Example 2: Hot Weather Application.
