The Round Determinate Panel (RDP) test has to be performed with a suitable flexural frame having proper stiffness and capacity, with a control console capable of applying load in displacement control.
Geo-Con proposes the following system comprising a high-stiffness flexural frame fitted with the 3-points test accessory and displacement transducers, together with an advanced, fully automatic control console with PC and software, all by our partners CONTROLS.
SIMPLEX, 350 kN cap. high stiffness flexure frame
High stiffness flexural frame designed for displacement controlled testing on advanced construction materials such as Fiber Reinforced Concrete (FRC) and sprayed concrete. This frame is suitable for testing various kinds of specimens (beams, flagstones, slab).
- High rigidity (200 kN/mm), especially suitable for testing FRC and sprayed concrete
- For testing different kind of specimens (beams, flagstones, slab) having max length 880mm.
- Suitable for testing Round panel dia.800mm to ASTM C1550
- Load measurement by load cell
- Piston return by counterweights
- Piston travel limit switch included

AUTOMAX Ultimate Automatic Computerized Control Console
The AUTOMAX ULTIMATE is CONTROLS’ latest Automatic Computerized Control Console for concrete, cement and steel rebar testing, allowing modular upgrades from basic failure tests to advanced displacement-controlled tests for Fibre Reinforced Concrete characterization. Its versatility allows to connect up to four testing frames, from 15kN to 5000kN, in compression and 500 kN in tension with the capability to test any kind of material and sample dimensions.
- Double frame control: expandable to four, with active frame selection via software.
- Wide range of testing methods: available through the addition of four easy-to-use software packages tailored to guide the operator through all test phases.
- Modular and expandable: precise control achieved by a high frequency (1 kHz) closed-loop PID control which adjusts oil flow every millisecond.
- High productivity: Dual stage Hydraulic Power Unit (HPU) with rapid approach, soft platen-to-specimen contact and highly accurate drop-by-drop oil flow control allowing high throughput of advanced test.
- Energy saving: Adopt the latest energy saving technology for lower power consumption and silent operation.
- Software integration package: to connect our HD camera TESTVIEW PRO, bar code reader, balance, calipers, etc.
- Ease of maintenance: automatic software calibration procedure.
- High accuracy: with 17-bit effective resolution (131,000 datapoint).
- Compact design with flexible height adjustment: W600 x D660 x H 1440/1580 mm
