Question: 1 / 400

The sample of concrete used for temperature determination must be rodded 25 times. True or False?

True

False

The statement that the sample of concrete used for temperature determination must be rodded 25 times is false. Temperature measurement does not require rodding to be performed, as it involves assessing the thermal state of the concrete mix at the time of testing. The focus for temperature determination is on the accuracy of the temperature probe and the placement of the thermometer in the concrete, ensuring it is adequately submerged to get a true reading.

Rodding is typically associated with tests that involve the compaction of concrete, such as the slump test, where a specified number of roddings is undertaken to ensure the mix is properly consolidated in the container or mold before measuring its properties. Therefore, it is important to recognize that temperature measurement is distinct from other tests, and no rodding is required for this specific determination.
