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. 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

Micro-deval abrasion testing machine is used to test the abrasion resistance of stones, aggregate, thus to evaluate the quality of aggregates.This machine is composed of drum, sealing cover, bracket, gearbox, motor, controller, it's kind of common aggregate test equipment.The machine consists of a steel frame suitable to house four 200 mm dia.x 154 mm length cylinders (EN 1097-1) .
