CONTROLS Testing Equipment at INTERMAT

Controls, a leading producer and supplier of testing equipment for the construction industry will participate at Intermat exhibition, Paris from 20-25 April, 2009. The company will make debut of its wide range of equipment at the show that include:

Concrete Technology

The AUTOMAX 5 automatic EN models (tested for stability) represent the more sophisticated and advanced evolution of the usual compression testers. The AUTOMAX-5 features the complete automatic test cycle with closed loop digital feedback. Once the specimen parameters have been introduced, it is sufficient to press the Start button to complete the test. The system applies automatically the correct load rate conforming to the information introduced by the control panel. The load value is continuously monitored and can be printed in the test report when connected to PC to certify the correct load rate application. The model on display at INTERMAT is the 2000 kN Mod. 50-C4652 for compression tests on cylinders up to a diameter of 160 x 320 mm and on cubes up to 200 mm.

BARTRACKER 58-E6102 Concrete covermeter

The BARTRACKER covermeter is able to accurately determine where the metal is, even when there are complicated crossings of mesh support structures and can locate tendon ducts deep within the structure. This takes the guesswork out of rebar and pipe location. The cover display screen shows you everything you need to know. Screens can be backlit for ease of viewing in dark conditions.

58-E4800 Ultrasonic pulse velocity tester to measure the velocity of propagation of ultrasonic pulses through concrete.

Road Testing

The application of this unit is for determining the rheologic properties of bituminous mixtures with tension, compression and dynamic loading. Base system capable of applying loads up to 14 kN comprising: test frame, pneumatic actuator, pneumatic interface, filters, regulators, connection etc. The load frame includes the IMACS Control and Data Acquisition System.

48-D5252 for the determination of the polished stone value

It is used to measure the resistance of road stone to the polishing action of vehicle tyres on a road surface. This machine provides a method of preparing polished stone specimens for use with the friction tester - (48-B0190 also on display) –when used in a laboratory environment.

76-B0252 Gyratory Compactor ICT 250 Series

The only European compactor approved by FHWA – U.S.A.

Soil & Rock Mechanics

AUTOTRIAX System: The automatic triaxial system expandible in subsequent modular step for: Effective stress, Stress path, Permeability and Unsaturated tests. Able to control up to three independent systems.

The AUTOTRIAX Automatic Triaxial System not only can perform Effective Stress triaxial tests, but is the unique and indispensable apparatus to perform the Stress Path triaxial test. In fact, this test is performed to allow the engineering to replicate the changes in stress conditions soil sample subjected to compression and extension both in loading and unloading status.

The permeability test and the unsaturated soil testing can be automatically performed with the AUTOTRIAX system using the appropriate accessories.

SHEARMATIC 27-WF2180 Automatic digital direct/residual shear machine

It incorporates a pneumatic closed loop system for the automatic application of the axial pressure by a high performance pressure regulator, with the main advantage of eliminating the manual loading of the dead weights.
