General Features:
The instrument measures a volume loss in a specimen under abrasion test and it’s used in tests such as: – paving stones – concrete slabs – slabs made of natural rocks – natural stone slabs.
The apparatus is basically composed of cast iron horizontal disc with a speed of 30 ± 1 rpm and a diameter of 750mm furnished of a 200mm test track to position a specimen.
Control panel with digital revolutions counter with automatic stop after 22 rotations. Abrasive Sand is must be ordered separately.

General Features:
Abrasion Tester used to determine the resistance to abrasion and wear of natural stones and concrete products by measuring the length of a groove produced on the specimen surface by disc with thickness of 70 mm that rotates at controlled speed and makes a constant pressure on the specimen. A charge of abrasive material must be interposed between the disc and the specimen. The abrasion wheel rotates at a speed of 75 rpm. The machine is equipped with digital counter which stops machine at the preset number of revolutions.
The abrasive corundum sand and calibration (Boulonnaise) marble are optional.

General Features:
Used for the determination of resistance to freezing and thawing by providing freezing / thawing in air/water. Freezing and Thawing Chamber can holding at constant temperature, heating and cooling at desired speeds, water intake and water discharge operations. There is a discharge valve for discharging operations.
3 models are available. Freezing and Thawing Chamber on Air, Freezing on Air and Thawing on Water Chamber and Freezing on Water and Thawing on Water Chamber.
Freezing and Thawing Chamber; automatically stops all operations when the end of the set cycle. If it is required to stay at a specified temperature at the end of the cycle, this can be done by adding to program before the program starts.
In the water thawing step; the water intake moment, the waiting period in water, the water discharge moment can be defined as parameters, each of which is a different step.
The cabin has a cover at the topand equipped with a piston pusher.The water intake tank is stand-alone.
The control unit is electronic and equipped with digital display with 0.1°C temperature resolution.
Software for data transfer to a computer is supplied complete with the cabinet, and data can be monitored during the tests.

Technical Specifications:
General Features:
Used to determine the flakiness index of the aggregates.Consists of an electrostatic painted frame and 5 mm diameter stainless steel bars. 50 mm aperture Sieve is not supplied with Complete Set and should be ordered separately.
Standards:
EN 933-3
Technical Specification:
General Features:
The unit provides a constant uniform shaking with automatic cycle test. Provides shaking action at the specified rate and stroke. Supplied complete with built in timer that stops the shaker at the end of the test. Two models are available HR-A0815 without Security Cabinet and HR-A0820 withSecurity Cabinet. When opening cabinet’s door during shaker working, a micro switch automatically stops the machine.
Standards:
EN 933–8, ASTM D2419, AASTHO T176
Technical Specification:
General Features:
Used to determine if aggregate is flaky; i.e. if thickness is less than 0,6 of nominal size.
Each sieve made from heavy gauge steel sheets in dimensions specified in the standards and coated with electrostatic paint.
