ENERGY ABSORPTION TEST ON SPRAYED CONCRETE SPECIMENS

Category:

STANDARDS: EN 14488-05 | UNI 10834
The equipment can be used only with the flexure Servo-Plus Evolution testing machine mod:
C090-07N Flexure high stiffness 200 kN capacity
C095N Flexure multipurpose 320 kN capacity
C096N Flexure polyframe 360 kN capacity.
Connected to the automatic servocontrolled system of load and displacement Servo-Strain mod C109-15N (see p. 283)
The equipment consists of:

C109-15N
FIRMWARE/SOFTWARE for:
– Measurement of deflection on fibre
reinforced concrete beams.
– Determination of toughness, first
crack strength and ductility.
– Energy absorption test on sprayed
specimens.
(see p. 18)

C090-14
SQUARE BASE FRAME
Dimensions 500×500 mm, complete with upper loading element,
for energy absorption tests on sprayed concrete specimens.
C090-19
HOLDER FOR TRANSDUCER
To be fixed to the high stiffness frame with square base.
S336-14
DISPLACEMENT TRANSDUCER, HIGH PRECISION
To be fixed to the high stiffness frame equipped with the square
base.
Travel: 50 mm
Full bridge at 350 Ohm
Indipendent linearity: < 0.1%
Standard sensitivity: 2 mV/V

CONCRETE PIPE TESTING MACHINE
Designed and manufactured to test concrete sewer and drain pipes used in drainage works, water and irrigation supply systems etc.
STANDARD: EN 1916 comparable to ASTM C301, C497 | BS 5911 | DIN 4035
The machine is composed of two parts:
Electro-Hydraulic loading and control system
Testing frame, steel made

C109-09N
ELECTRO-HYDRAULIC LOADING AND CONTROL
SYSTEM, 1000 KN CAPACITY
– Double action alloy steel ram + cylinder.
– Ram travel: 400 mm
– The ram is ground.
– Upper attachment for steel frame cross-beam coupling.
– Spherical seat fixed to the ram for an uniform loading.
– Hydro-Plus Evolution loading and control cabinet, complete with
hydraulic multipiston power pack group, maximum pressure safety
valve, decompression valve, oil flow control valve granting smooth
and accurate load pace.
– Computerized graphic display Cyber-Plus Evolution unit mod.
C109N (technical details: see p. 224) with software for the acquisition,
visualization, processing, printing and saving of the test
data and certificates.
– Electric load cell 1000 kN capacity, for accurate load measurement
directly from the ram.
– Two flexible high pressure hoses, to connect the cylinder to the
hydraulic power pack.
Power supply: 230V 1ph 50Hz 1000W
Dimensions: 500 x 530 xh 1300 mm
Weight: 150 kg approx.

C093-05N
TESTING FRAME, STEEL MADE
– Pipe max. diameter (external): 2600 mm
– Pipe min. diameter (external): 450 mm
– Pipe max. length: 2500 mm
– Lower bearers: 2500 mm long
– Upper crossbeam: 2500 mm long
– Frame of structural steel, bolted together with high strength bolts,
so it can be easily assembled/disassembled for delivery or for site
displacements. The frame has to be locked to a concrete base to
be prepared by the customer.
– Two upper crossbeams, raised and lowered by a motor two speed
operated winch. The upper frame crossbeam is locked in position
by pins inserted through the columns.
– Two lower bearers supporting the pipe to be tested.
The bearers are supplied both flat and “V” shaped as requested
by the EN 1916 Spec.
– Upper loading beam, floating on a seat.
Power supply of the winch: 230/400V 3ph 50Hz 2000W
Frame dimensions: 3700x2500x6900 mm approx.
Weight: 7000 kg approx.
