ACI Concrete Field Testing Technician - Grade I Practice Exam

Can the temperature of concrete be measured in a wheelbarrow?

1. Yes

2. No

3. Only if the wheelbarrow is insulated

4. Only for small batches

The correct answer is: Yes

The temperature of concrete can indeed be measured in a wheelbarrow. Measuring the temperature in such a setting is feasible because the primary concern is to obtain an accurate reading of the concrete temperature before it is placed. The temperature at this point can provide critical information regarding the curing process and the setting time, which is important for ensuring quality control and appropriate handling of the concrete. Using a thermometer or a temperature probe, one can easily insert it into the concrete mix in the wheelbarrow to get a reliable temperature reading. The key is to ensure that the probe is surrounded by the concrete mixture for an accurate measurement, without interference from external factors like ambient temperature. While other options suggest conditions under which measurement might be possible, they do not reflect the general capability to measure concrete temperature in a wheelbarrow under standard conditions.
