ACI Concrete Field Testing Technician - Grade I Practice Exam

What happens if the final concrete level exceeds the measure after consolidation?

1. It is acceptable

2. It must be discarded

3. It must be evaluated

4. It should be trimmed to the measure's level

The correct answer is: It should be trimmed to the measure's level

When the final concrete level exceeds the measure after consolidation, trimming it to the measure's level is the appropriate action to take. This process ensures that the sample accurately reflects the intended volume for testing, as the precise measurement is critical for evaluating the concrete's properties. Exceeding the measure can lead to inaccurate test results, which are essential for assessing mix quality and compliance with specifications. By trimming to the correct level, the technician eliminates excess material that could skew results, ensuring that the sample remains representative and adheres to the standards set forth by ACI guidelines. Proper sample preparation is fundamental in concrete testing, and maintaining accurate measurement is key to obtaining reliable data.
