ACI Concrete Strength Testing Technician Practice Test

The final report should include both the average width and depth to the nearest:

1. 0.01 inch

2. 0.10 inch

3. 0.05 inch

4. 0.15 inch

The correct answer is: 0.05 inch

The final report in concrete strength testing must adhere to specific measurement precisions to ensure accuracy and reliability in reporting. The average width and depth of the samples being tested are critical parameters that directly influence the assessment of concrete strength. Recording these dimensions to the nearest 0.05 inch provides a balance between sufficient precision and practical relevance for most testing scenarios. This level of detail is adequate for typical concrete applications, allowing for meaningful comparisons and evaluations without implying an unnecessary level of accuracy that might not be achievable due to inherent material variability. Ensuring measurements are taken and reported consistently within this threshold supports standardization and helps maintain the integrity of the test results.
