Flakiness and Elongation

Flakiness Index Sieve SetFlakiness Index Sieve Set BS k

 UTA-0410

When an aggregate particle has a thickness less than 0.6m of its mean sieve size, it is considered flaky. The aggregate to be classified is separated into seven sieve fractions from 6.3 to 63 mm and each fraction is examined separately. Each sieve is made from heavy gauge steel and is coated with electrostatic paint. The dimensions of each sieve comply with the relevant International Standard. The accuracy of the slot size is better than 0.1 mm. 

UTA-0410 Flakiness Index Sieve Set consists of 7 sieves.

For sample preparation 6.3, 10, 14, 20, 28, 37.5, 50 and 63 mm aperture sizes test sieves should be ordered separately.

Grid Sieve SetGrid Sieve Set 1 k

 UTA-0420

The Grid Sieve Set is used to determine the flakiness index of the aggregate.

All the sieves include an electrostatically painted frame and stainless steel bars with a 5 mm diameter.

For sample preparation 4.5, 6.3, 8, 10, 12.5, 16, 20, 25, 31.5, 40, 50, 63, 80 and 100 mm aperture sizes test sieves should be ordered separately.

Length GaugeUTA-0450 Thickness Gauge Flakiness Index BS

 UTA-0455

The Length Gauge (Elongation Index BS), is used to measure the elongation index of aggregates.  When the length of the particle is more than 1.8 of the midsize of the sieve fraction, it is considered elongated. The aggregate to be classified is separated into six sieve fractions from 6.3 to 50 mm and each fraction is examined separately.

 

Thickness GaugeUTA-0455 Length Gauge Elongation Index BS 2

 UTA-0450

The Thickness Gauge is used to determine if the aggregate particles are to be considered as flaky, i.e. their thickness is less than 0.6 of their nominal size.

The aggregate to be classified is separated into seven sieve fractions from 6.3 to 63 mm, and each fraction is examined separately. Slot sizes are:

  • 4.9 x 30 mm
  • 7.2 x 40 mm
  • 10.2 x 50 mm
  • 14.4 x 60 mm
  • 19.7 x 80 mm
  • 26.3 x 90 mm
  • 33.9 x 100 mm
