MEASUREMENT OF DEFLECTION ON FIBRE REINFORCED CONCRETE BEAMS 100X100X400(500) MM AND 150X150X500(600) MM
DURING FLEXURE TEST.
STANDARDS: EN 14488-3 | ASTM C1609, C1018

 

DETERMINATION OF TOUGHNESS, FIRST CRACK STRENGTH (CRACK OPENING) AND DUCTILITY OF FIBRE REINFORCED
CONCRETE. STANDARDS: EN 11039-2, EN 14651
FLEXURAL STRENGTHS (FIRST PEAK, ULTIMATE AND RESIDUAL) OF FIBRE REINFORCED BEAM SPECIMENS.
STANDARD: EN 14488-3
The equipment can be used only with the Servo-Plus Evolution
machines.
Connected to the Servo-Strain Software/Firmware mod. C109-15N
(see p. 283) for the automatic management of load and displacement.

It is necessary to contact Matest representative for the appropriate
machine selection according to the FRC application.
The equipment consists of:
C090-15
DEFLECTION MEASUREMENT DEVICE
STANDARDS: EN 14488-3 | ASTM C1609, C1018

This device is fixed directly on the fiber reinforced concrete beam
under test. The device is placed between the loading bearers of a
flexure frame or of a flexure device in a compression frame.
The test is performed by applying a flexural load to the concrete
beam with load and displacement control and with automatic
deflection measurement of the loaded specimen.
It is possible to test fibre reinforced concrete beams 100x100x400
or 500 mm and 150x150x500 or 600 mm dimensions.
The deflection device is made with chromed finishing; it is supplied
complete with transducer holders, vertically positioned on the two
opposite sides of the beam, but without the two transducers, for
the measurement of deflection (mod. S336-11), and without the
fork form transducer (mod. C090-16) to be ordered separately.
Dimensions: 300x450x300 mm
Weight: 8 kg approx.
S336-11
DISPLACEMENT TRANSDUCER, HIGH PRECISION

STANDARDS: EN 14488-3 | ASTM C1609, C1018
To be attached to the device C090-15 for the measurement of
deflection and determination of toughness on fibre reinforced concrete
beams. Travel: 10 mm
Complete with cable and connector.
Two transducers are required.
C109-15N
FIRMWARE/SOFTWARE for:
– Measurement of deflection on fibre reinforced concrete beams.

FIRMWARE/SOFTWARE for flexural stengths (first peak,
ultimate and residual) EN 14488-3 (see p. 18).

C090-20
DATUM BLOCK, square, to be glued on the concrete beam
surface for the deflection measurement on the two opposite sides
(CTOD). Pack of 24 pieces.
C090-16
FORK FORM TRANSDUCER
STANDARDS: EN 11039-2, EN 14651
For the measurement of the Crack Mouth Opening Displacement
(CMOD) and the Crack Base, Medium and Tip Opening Displacement
(CTOD). Measuring range: 5 mm
Complete with cable and connector.

C090-18 DATUM BLOCK, to be glued on the lower side
of the concrete beam for the first crack strength test
(CMOD). Pack of 24 pieces.
