What must be done after the temperature of the concrete is read?

Reporting the temperature is a crucial step after measuring the temperature of the concrete because this information is essential for ensuring the quality and consistency of the concrete mix. Temperature readings can significantly impact the strength, workability, and curing process of the concrete. By documenting the temperature, stakeholders can assess whether the concrete mix adheres to the specified requirements set by relevant standards or project specifications. This helps ensure that the concrete is used under optimal conditions for setting and curing.

In contrast, while cooling the concrete or taking a new sample could be considered necessary under certain conditions, these actions are not universally required after simply reading the temperature. Calculating the average temperature might be useful in certain contexts but isn't a standard immediate action following a single temperature reading. The most critical action to take after reading the temperature is to report it, ensuring that all parties involved are informed and can make appropriate decisions based on that data.
