The correct temperature range for storing flexural test specimens in lime water is indeed 23 +/- 2 degrees Celsius. This specific temperature range is critical for ensuring consistent curing conditions, which directly influences the properties of the material being tested. Maintaining a controlled temperature is essential because deviations can lead to variations in hydration and interstitial pressures, affecting the microstructure and mechanical properties of the specimens. By storing the specimens at this specified temperature, one can minimize external influences, ensuring that the test results reflect the true performance of the material under standard conditions. The +/- 2 degrees Celsius margin allows for practical variances that can occur in laboratory settings while still adhering to the established standards for flexural testing.
