What is the minimum and maximum temperature of concrete that can be poured into a concrete structure?

Question

Accepted Answer

The minimum and maximum temperature of concrete that can be poured into a concrete structure depends on various factors.

The minimum temperature of concrete should be above 5 degrees Celsius to ensure proper hydration and strength development.
The maximum temperature of concrete should not exceed 32 degrees Celsius to prevent excessive heat and potential cracking.
Extreme temperatures can affect the setting time, workability, and overall quality of the concrete.
In cold weather, measures like using heated aggregates and water, insulating forms, and curing with blankets may be necessary.
In hot weather, techniques like using chilled water, shading the concrete, and adding set retarders can help control temperature.
Specific temperature limits may vary based on project specifications, local climate conditions, and the type of concrete being used.
