What is the volume range for a calibration cylinder used for air content testing?

1-4%

1-5%

1-6%

The volume range for a calibration cylinder used for air content testing is typically between 1-6%. This range is essential for accurately determining the air content in fresh concrete mixtures, ensuring that the results fall within the expected parameters for concrete quality control. The calibration cylinder allows for precise measurements of air content, which is vital for understanding the performance characteristics of the concrete, such as its durability and resistance to freeze-thaw cycles.

The specifications for air content testing emphasize the importance of using a calibration cylinder that can accommodate the necessary volume of air for accurate readings. A volume that exceeds or falls short of this range could lead to erroneous conclusions about the air content, potentially compromising the integrity of the concrete being tested.
