Triaxial Testing Equipment

Triaxial testing is conducted to measure the mechanical properties of soil, sand, clay, and other granular materials.
Typical triaxial tests involve confining a sealed cylindrical soil specimen, with a height-to-diameter ratio of 2:1, into a pressurised cell to simulate defined stress conditions. The specimen is then sheared until failure which leads to the determination of its shear strength properties. The specimen is initially saturated, then consolidated and finally sheared, mostly under compressive conditions.
