Vebe’s Consistometer – Vebe consistometer method is based on the same principle of the simple
slump cone test method, for the determination of the workability of concrete, but it
has the advantage of a mechanized action after removing the slump cone, the concrete
undergoes a vibration to determine its slump. A space disk set in contact with the upper
surface of the wet concrete, gives the operator the opportunity to determine when the
compaction is complete. The operator will count the time necessary to complete the
requested vibration, so as to get an indication of the workability of the concrete.
Compacting Factor Apparatus – designed to undertake a more precise and sensitive test procedure
than the simple slump test.
K-slump Tester – to determine the degree of compaction and the workability of fresh concrete. Used
for in-situ measurements of inside test moulds. Test results can be correlated against
the slump values.
Walz Consistometer – to measure the consistency of fresh concrete.
Flow Table – used to determine the workability of concrete.
Kelly Ball Apparatus – it is used to determine the workability of fresh concrete. The ball is lowered
into the concrete and the penetration measured. It can be used on site or in laboratory.
Concrete Workability Meter – the concrete workability meter (also known as plastometer) is
designed to test concrete for dynamic workability.
Plasticity Meter – used for quick and easy measurement of the plasticity of mixtures especially
concrete, and so to detect rapidly any excess of water. The measuring system is related to
the shear strength applied by a three blade heads to the mixture under test.
Concrete Penetrometer – used to determine the setting time of the mortar fraction in concrete mixes
with the slump greater than zero, by testing mortar sieved from mix.
Air Entrainment Meter – it records directly the percentage of air enclosed in freshly mixed concrete
by operating according to the air pressure principle.
Unit Weight Measure – used to determine the weight per cubic meter of freshly mixed and
compacted concrete.
Joisel Apparatus – used to separate the various elements of the fresh concrete such as cement, sand,
and aggregates.
RAM (Rapid Analysis Machine) – used for the determination of cement content in fresh concrete ,
coarse and fine aggregate, fly ash and GGBF slag content can also be determined.
Moulds – used in molding.
Vibrating Tables – used for the compaction of concrete specimens in laboratory.
Specimen Grinding Machine – designed to grind and polish cubic and cylindrical specimens of
concrete, rocks, and natural stones.
Curing Tanks – used for concrete specimens.
Core Drilling Machines – design to remove a cylinder of material much like a hole saw.
Specimen Cutting Machine – used to cut concrete specimens and any type of construction materials
like blocks, tiles, pipes, rocks cores etc.
Ultrasonic Pulse Velocity Tester – to measure materials characteristics by using ultrasonic pulses.
