To what precision should the temperature of the concrete be reported?

The temperature of the concrete should be reported to a precision of 1 degree Fahrenheit. This level of precision is generally deemed sufficient for most concrete testing and monitoring purposes in accordance with ASTM standards. Reporting temperature at this precision allows for consistency in documentation while ensuring that small fluctuations that may not significantly impact the concrete's performance are not overstated.

Achieving a balance between precision and practical application is important, as more precise measurements (like 0.1 degree) could lead to unnecessary complications and make reporting cumbersome. A precision of 2 degrees Fahrenheit is too coarse and may overlook important temperature changes that could affect the setting and curing process of the concrete. Thus, 1 degree Fahrenheit serves as a practical standard in the field of concrete testing.
