What does the temperature of concrete at the time of batching depend on?

The temperature of concrete at the time of batching primarily depends on the ambient temperature. This is because the surrounding environment significantly influences the temperature of all its components, including the water, aggregates, and cement used in the mix. If the ambient temperature is high, all materials are likely to warm up, resulting in higher concrete temperatures. Conversely, in cold weather, the materials can be significantly cooler, affecting the overall temperature of the concrete mix.

While factors like the amount of water, type of aggregates, and mixing time can influence the temperature indirectly or affect the workability and curing of the concrete, they do not directly dictate the temperature of the concrete at the time of batching to the extent that ambient temperature does. Understanding this relationship is crucial for ensuring proper setting and curing of the concrete, which is essential for achieving desired strength and durability in concrete structures.
