Toni Technik, the Zwick Roell Group's construction materials manufacturer, has delivered the 1,000th Tonitrol control system to MPA Kaiserslautern.
This was supplied in conjunction with a four-column flexure testing machine from the Tonitop range, designed for high-accuracy deformation measurement.
The machine will be used extensively for testing steel-fibre-reinforced concrete to the regulations of the German Concrete Association (DBV) and the German Sub-Committee for Reinforced Concrete (DafStb).
These regulations can be challenging for testing machine manufacturers, as this strain-controlled test calls for a high proportion of the stored energy from the frame to be controlled in fractions of a second.
However, the tests are said to be necessary to allow use of steel-fibre concrete as a statically reinforced building material.
The four-column flexure testing machine has a maximum load capacity of 300kN, possesses extremely high frame stiffness and fully automatic height adjustment and can accommodate flexure tests to a maximum of 2500mm x 1100mm.
The universal computer-controlled Tonitrol control and measurement system regulates load, travel and strain as well as performing monitoring and evaluation in tests on construction materials.
Together with the high-quality, stiff load frame and Testxpert materials testing software from the Zwick Roell Group, the Tonitrol microprocessor system forms an all-round construction materials testing system with long-term upgradability.
