STANDARDS: BS 1377:7, BS 1377:8 | ASTM D2850, D4767, D7181 | NF P94-070, P94-074 | CEN-ISO-TS 17892
MAIN FEATURES
Automatic execution of 5 independent triaxial
tests from start to finish.
Type of tests: total and effective stress, standard
stress path, optional K0 and optional permeability.
Servo feedback controlled precision pressure
(Pressurematic) generation system.
Real time graphing and configurable real time
transducers.
Pre-programmed user-friendly “Method files”
through the TestLab Software.
Compact and versatile for improving productivity and
cost effectiveness.
No need of air source.
Matest TRIAXLAB is an outstanding system specifically designed for
advanced soil testing.
This system can be used from educational to construction engineering
laboratories to reduce to the absolute minimum any form of manual
intervention.
Based on the unparalleled performance of CDAS and flexibility of
TestLab Software, the new MATEST TriaxLab Automated System is
the optimized system to perform automatically total and effective
triaxial tests such as:
CD Consolidated Drained test
CU Consolidated Undrained test
UU Unconsolidated Undrained test
Standard stress path
Optional K0 tests
Optional Permeability tests
The TRIAXLAB automated system basically consists of 3 major
groups:
Load frame and triaxial cell with accessories
Control system based on the CDAS Control and Data Acquisition
System and TestLab Software controlled by PC
Data Acquisition System comprising:
– 1 load cell for axial force
– 1 displacement transducer for axial displacement
– 2 pressure transducers for cell pressure and back pressure
– 1 pressure transducer for pore pressure
– 2 Pressurematic for pressure / volume change
Triaxlab – Advanced Technology for effective Triaxial Tests
To suit the specific customer’s requirements the MATEST TriaxLab
Automated System basic configuration can be modified by adding
or removing the hardware elements which are controlled and
monitored under a closed-loop integrated system with the CDAS
and TestLab Software.
Pre-programmed “Method files” offer the operator the unique
opportunity to run a range of tests without the need for specific
computer programming. The possibility to customize the Method
files is also given to the operator granting ultimate flexibility and
versatility.
