FLAKINESS GAUGE - COMPLETE S.S. (BS - 812)

Model Number : TM-191-SSBS

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. Particle is flaky when its thickness (smallest dimension) is less than 0.6 of the mid-size of the sieve fraction.

Compliance with following International Standards

BS 812-105.1, BS EN 12620

Purpose:

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. Particle is flaky when its thickness (smallest dimension) is less than 0.6 of the mid-size of the sieve fraction.

Significance & Use:

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.

Construction Details:

  1. It consists of a  Stainless Steel frame with M.S. sliding panel.
  2. The panel has slots, which are accurately cut, in standard different length and width.
  3. Gauge has seven labeled slots for rapid hand trying of particles from each of the seven sieve cuts.
  4. Square hole perforated plate with 300 mm diameter
  5. Having following Normal Aperture size as per British Standards : 63, 50, 37.5, 28, 20, 14, 10, 6.3 mm
