These tests are significantly affected by the actual frame stiffness therefore the relevant international Standards state stiffness limits which are exceeded by this new model (better than 200 kN/mm).

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.

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.

The horizontal daylight accommodates large specimens (slab, flagstones), concrete beams and kerbs long up to 650 mm. Orthogonal mode is meant to be used to test long specimens having more than 650mm length. Two models are available, either with pressure transducer or with load cell, both fitted with piston travel limit switch and connection kit to separate control console.

Main Features:

High rigidity (200 kN/mm), especially suitable for testing FRC and sprayed concrete

Max span between lower rollers: 1m

Piston return by counterweights

Piston travel limit switch included

Load measurement by load cell or pressure transducer

Double testing mode: parallel and orthogonal 

For testing different kind of specimens (beams, flagstones, slab).
