Flakiness Gauge Calibration Services

A flakiness (thickness) gauge is used to determine whether aggregate particles are classified as flaky, meaning their thickness is less than 0.6 times their nominal size. To perform the test, the aggregate sample is first separated into standard sieve fractions, typically ranging from 6.3 mm to 63 mm. Each fraction is then checked using the gauge slots to identify particles that fall below the specified thickness, helping assess the quality and suitability of aggregates for construction purposes.
