Description
The AZA1008 Hoek Triaxial Cell consists of a heavy-duty stainless steel pressure chamber housing a cylindrical rock specimen enclosed in a flexible rubber membrane. A hydraulic confining fluid uniformly applies lateral pressure while an axial load is applied vertically through a loading piston, accurately reproducing true three-dimensional stress conditions.
The system measures peak compressive strength, stress–strain behavior, and elastic moduli. It supports integration with LVDTs, strain gauges, and digital load indicators for real-time data acquisition and graphical output. The unit operates seamlessly with both manual and servo-controlled testing machines.
