• Used to determine whether aggregate particles are flaky.

• Particles are classified as flaky if their thickness is less than 0.6 times their nominal size.

Length Gauge

• Measures the length of individual aggregate particles to classify elongation.

• Particles are considered elongated if their length is more than 1.8 times their nominal size.

• Note: Length Gauge test is not applicable to material retained on a 63.0 mm BS test sieve.
