Triaxial Test for Rock Mechanics

Triaxial Test This machine incorporates the Advanced Digital Readout ( ADR) . The ADR is designed to minimise data entry during normal testing procedures and is fully described in the concrete/ rock section. These machines are specially adapted for use with Hoek Triaxial Cells Hoek Cell ADR 1000 kN Compression Machine   High stability load frame (   Calibration by KAN Specification : Capacity : 1000 kN Ram Travel : 50 mm Display : Digital Read out Platen diameter : 178 mm Accuracy : Better than + / - 1% over upper 90% of working range Hoek Cell ADR 1000 Compression Machine supplied complete with digital readout, power pack, special upper and lower platens and gates.( For 220 – 240VAC, 50 Hz, 1 ph Hoek Cells   For use with pressures up to 70 MPa   Fast and effective specimen handling Hoek cells detailed in this section have been designed to accept the nominal core sizes specified in International Standards. A cell for 1.5 inch diameter specimens is also offered. The basic cell comprises a steel body and two steel end caps which are screwed to the body of the cell when in use. The body incorporates two self-sealing couplings; one for connecting to the hydraulic pressure system, the other for de-airing the cell chamber and for the attachment of pressure measurement devices if required. Hardened and ground spherical steel pistons and two jackets of the same diameter as the specimen are supplied. Hydraulic Constant Pressure Systems Successful triaxial tests on rock specimens require a means of providing a continuous constant confining pressure. The two pressure systems described have been developed to provide an accurate self-compensating pressure which can be applied quickly and effectively to the range of Hoek Cells. Hand-operated Pressure System Specification : Pump : Single piston Maximum pressure : 70 Mpa Gauges : 200 mm diameter, scale marked 0-60 MN/ m2 Weight : 15 kg Accessories : ( Optional) * Hoek Cell Specimen Extruder Specimen Extruder. Extrudes the specimen from its jacket without the need to drain the confining fluid. Incorporates a rack and pinion mechanism mounted in a steel body, with adjustable back plate. Supplied without extruder adaptor sets. Weight 11 kg Extruder Adaptor Sets Enables the specimen extruder to be used with the complete range of Hoek Cells. Each set comprises back plate adaptor, cell body support and extruder shaft head. Note : Local Product ( made in Indonesia) Include Calibration by KAN
