What is the standard temperature for conducting specific gravity tests on aggregates?

The standard temperature for conducting specific gravity tests on aggregates is 20 degrees Celsius (68 degrees Fahrenheit). This temperature is established as a reference point to ensure consistency and reliability in test results. Conducting tests at this specific temperature helps mitigate the impact of temperature fluctuations on the properties of the aggregate, which can affect density and other measurements.

For specific gravity testing, adhering to this standard temperature ensures that the results are comparable across different laboratories and testing scenarios. If aggregates were tested at significantly different temperatures, it could lead to variations in the readings, compromising the accuracy and reproducibility of the data. Therefore, maintaining the testing conditions at 20 degrees Celsius is vital for obtaining valid and reliable specific gravity measurements.
