C) What is temparature of Concrete Casting ??

Question

Accepted Answer

The temperature of concrete casting is an important factor that affects its strength and durability.

The temperature of concrete during casting should be within a specific range to ensure proper hydration and curing.
The ideal temperature for concrete casting is typically between 50°F and 90°F (10°C and 32°C).
If the temperature is too low, the hydration process slows down, leading to delayed strength development.
If the temperature is too high, the hydration process accelerates, which can cause cracking and reduced strength.
Extreme temperatures can also affect the workability and setting time of concrete.
In hot weather, measures like shading, cooling aggregates, and using chilled water can help control the concrete temperature.
In cold weather, insulation, heating, and using hot water or admixtures can prevent freezing and promote proper curing.
Monitoring and controlling the concrete temperature during casting is crucial for achieving desired strength and durability.
