The Triaxial Cell Test Apparatus with 30-Speed Control is a geotechnical testing device used to determine the mechanical properties of soil, particularly shear strength, cohesion, and angle of internal friction under controlled stress conditions.

• 30-Speed Control System: Offers high-resolution adjustment of axial strain rates, allowing for a wide range of testing speeds to simulate various field conditions, from very slow consolidation tests to faster loading scenarios.
• Pressure Chamber (Triaxial Cell): A transparent, high-strength acrylic or metal cell houses the soil sample, allowing confining pressure to be applied uniformly via fluid.
• Loading Frame: Precision motor-driven loading mechanism for applying vertical stress with high accuracy.
• Specimen Dimensions: Typically supports standard sample sizes like 38 mm diameter × 76 mm height and others.
• Measurement Systems: Equipped with load cells, displacement transducers (LVDTs), and pressure transducers for accurate measurement of load, deformation, and pore pressure.
• Pore Pressure and Volume Change Monitoring: Compatible with systems for measuring and controlling pore water pressures and volume changes during CU and CD tests.

• IS: 2720 Part 11 & Part 12
• ASTM D2850
• ASTM D4767
• BS 1377
