ACI Concrete Field Testing Technician - Grade I Practice Exam

The temperature of concrete is reported to the nearest _____ degrees F.

1. 1 degree F

2. 2 degrees F

3. 5 degrees F

4. 10 degrees F

The correct answer is: 1 degree F

The temperature of concrete is typically reported to the nearest 1 degree Fahrenheit because precision is important in ensuring proper curing and hydration of the concrete mix. Concrete's temperature can significantly affect its workability, setting time, and overall strength. Recording the temperature to the nearest degree helps technicians monitor conditions closely during the placement and curing process. This level of accuracy is necessary to maintain consistent quality control, particularly in varying environmental conditions. Reporting to a broader range, such as 2, 5, or 10 degrees, may not provide sufficient specificity needed for effective quality management in concrete field testing.
