9 Thickness and Length Gauge(good quality)

Order Code: 20214342.1.9

Category: General Lab Equipment II

Used to determine the percentage of particles in a coarse aggregate material that have a thickness (smallest dimension) of less than one-half of the nominal size.



SPECIFICATION

 

  • Particle is flaky when its thickness (smallest dimension) is less than 0.6 of the mid-size of the sieve fraction.
  •  Aggregates which are flaky and/or elongated will often lower the workability of a concrete mix and may also affect long term durability.
  • In bituminous mixtures, flaky aggregate makes for a harsh mix and may also crack and break up during compaction by rolling.
