How deep must the sensor of the temperature measuring device be submerged in freshly mixed concrete?
2 inches [50 mm]
3 inches [75 mm]
4 inches [100 mm]
5 inches [125 mm]
The correct answer is: 3 inches [75 mm]
The depth to which the sensor of the temperature measuring device must be submerged in freshly mixed concrete is crucial for obtaining an accurate representation of the concrete's temperature. Submerging the sensor to a depth of 3 inches [75 mm] ensures that the reading is taken from within the mass of the concrete, minimizing the influence of ambient temperature or surface variations. At this depth, the sensor is less likely to be affected by factors such as air pockets, evaporation, or exposure to the elements, which could lead to inaccurate measurements. This standard practice is intended to provide a reliable temperature reading that reflects the thermal conditions existing within the concrete mix, thereby facilitating accurate assessment for quality control during concrete placement. Choosing a depth that is too shallow may yield erroneous readings, resulting in potential misinterpretations of the curing conditions.
