Is it acceptable to measure the temperature of concrete in a wall form?

1. True

2. False

3. Only if there is sufficient space

4. Only if the form is made of metal

The correct answer is: True

Measuring the temperature of concrete in a wall form is indeed acceptable because it provides valuable information about the curing process and helps ensure that the concrete achieves its intended strength and durability. Temperature affects the hydration process of cement, and maintaining the concrete within specified temperature limits is crucial for optimal curing. Conducting temperature measurements within the wall form helps identify potential issues, such as thermal cracking or insufficient curing, allowing for timely corrective actions. It is important to note that measuring the temperature in this location must be done carefully to ensure accurate readings and avoid any damage to the forms or the concrete itself. The other options highlight different conditions or restrictions that do not apply universally, as temperature measurements can be taken effectively regardless of those factors. For instance, whether there is sufficient space or whether the form is made of metal may influence the ease of measurement, but they do not restrict it fundamentally.
