ACI Concrete Field Testing Technician - Grade I Practice Exam

Question: 1 / 400

What is the accuracy requirement for the temperature measuring device?

+- 1 degree F [+- 0.5 C]

The accuracy requirement for the temperature measuring device in the context of concrete field testing is set at plus or minus 1 degree Fahrenheit (plus or minus 0.5 degrees Celsius). This level of accuracy is crucial because it ensures that the temperature of the concrete mix can be reliably measured for various tests and applications. Temperature can significantly affect the curing process and the overall quality of the concrete, so precise measurements are essential for maintaining the integrity of the testing and the resulting concrete structure. Using a device with this specified accuracy helps minimize errors and enables technicians to make necessary adjustments to the mix or curing conditions if the temperature is outside the recommended range. This requirement aligns with standard practices in the industry, which prioritize accuracy to achieve consistent and reliable results in concrete testing.
