Description:
This high stiffness flexural frame has been designed to have a double testing mode, parallel and orthogonal.
Parallel mode is meant to be used for displacement controlled testing on advanced construction materials, e.g. fiber reinforced concrete (FRC) and sprayed concrete.
These tests are significantly affected by the actual frame stiffness (set at 200 kN/mm by the relevant international Standards). Our model exceeds the Standards requirement with its 350 kN/mm capacity thanks to its specific layout which keeps the specimen aligned with the frame crossbeams, making most of its structural rigidity.
This remarkable result comes from the frame sections but it is also derived from the particular layout which keeps the specimen aligned with the frame crossbeams maximizing structural rigidity.
Orthogonal mode is meant to be used to test long specimens having more than 880mm length.
The horizontal daylight accommodates large specimens (slab, flagstones), concrete beams and kerbs long up to 880 mm.
The frame is fitted with high precision load cell (recommended for FRC testing), with piston travel limit switch and connection kit to the control console. Bearers not included. Please see accessories.
Bearers not included. Please see accessories.
Frames includes two rulers, two additional rulers are available on request. Rulers with graduations in inches are available on request.
