ACI Concrete Strength Testing Technician Practice Test

If a test specimen is damaged prior to the test, what is the recommended action?

1. Proceed with the test to observe potential results

2. Discard the specimen and select a new one

3. Make temporary repairs and test

4. Inform the supervisor but continue testing

The correct answer is: Discard the specimen and select a new one

When a test specimen is damaged prior to the test, the recommended action is to discard the specimen and select a new one. This procedure ensures that the integrity of the test results is maintained. Testing a damaged specimen could yield inaccurate, misleading results that do not reflect the actual properties of the concrete. Concrete strength testing relies on the ability of the specimen to represent the conditions and qualities of the batch from which it was taken. Any damage prior to testing could compromise the integrity of the specimen, such as affecting its physical or mechanical properties, which are critical for obtaining reliable strength measurements. By choosing to discard the damaged specimen, you ensure that the test results will be valid and meaningful, ultimately upholding quality assurance standards in concrete testing. This practice supports the accuracy and reliability necessary for effective quality control.
