Aggregate and Rock
 

Grid Sieves

Standards: EN 933-1, EN 933-3

Grid Sieves are used to determine the flakiness index of the aggregates. Made of electrostatic steel frame and 5 mm diameter stainless steel parallel bars.

Flakiness Sieves

Standards: BS 812

Each sieve made from heavy gauge steel sheets in dimensions specified in the standards and coated with electrostatic paint.

Flakiness Gauge

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

Length Gauge

Standards: BS 812

Length Gauge classifies aggregate elongation by measuring the length of individual particles. Aggregate particles are considered elongated when their length is more than 1.8 of their nominal size. Length Gauge test is not applicable to material retained on 63.0 mm BS test sieve.

Shape Index Gauge

Standards: EN 933-4

Shape Index Gauge is used to determine the shape factor of individual aggregates by comparing the ration of length to
width.

Particle Density (specific gravity) and Water Absorption Sand Absorption Cone and Tamping

Specific Gravity Frame and Buoyancy Balance

Standards: BS 812, ASTM C127, AASHTO T85, EN 1097-6,

This method is used to determine the aggregates specific gravity. The robust frame is designed to support the buoyancy balance. The lower part of the frame incorporates a moving platform, which carries the water tank allowing the test specimens to be weighed in both air and water.

Bulk Density Measures

Standards: BS 812-2, 3797, EN 1097-3, 12350-6, ASTM C138,
C29

 

The Bulk Density Measures are used to determine the loose bulk density and voids of aggregates. They are made from heavy steel gauge and specially coated against corrosion.

Digital Point Load Apparatus

The point load tester is used to measure rock strength in the
field
or laboratory. A load frame, hydraulic jack and digital
display
are mounted on the base of a carrying case.

With this point load tester, samples up to 4" (101.6mm)
diameter
can be tested on 2 conical points. A graduated scale indicates distance between conical points and is also used to measure specimen diameter. Applied load is digitally displayed
to
0.001kN; accuracy is ±1%; range is 0 to 56kN. Display
shows
maximum load and will also read in lb and tons.
