Triaxial Testing Equipment

Technicians prepare and mount undisturbed or remolded specimens in a test cell pressurized with water to create a confining pressure around the specimen. The test cell is placed in a Load Frame to gather information about shear resistance, strength, cohesion, and to predict slope stability and structural foundation behavior. Tests can be conducted with specimens in unconsolidated-undrained conditions using ASTM D2850 methods, consolidated-undrained in accordance with ASTM D4767, or consolidated-drained conditions meeting ASTM D7181.

• Triaxial Cells are used with Load Frames and can be adapted to other soil testing equipment.
• Triaxial Cell Accessories are designed for use with Load Frames and Control Panels and are available individually or as part of a complete set of products used in triaxial testing.
• Triaxial Control Panels regulate and monitor air and fluid pressures in the Test Cells through a system of burettes, valves, regulators, and can also be used for hydraulic conductivity/flexible wall permeability testing of soils. Master or Auxiliary Control Panels offer greater flexibility to set up your system.
• Triaxial Load Frames are used for loading specimens for triaxial testing and meet ASTM standards.
• Load & Displacement Measurement products are available in either digital or analog options, and measure load and sample displacement during triaxial soil testing in accordance with ASTM D2850, D4767, and AASHTO T 297.
• Triaxial Data Acquisition Software works with the Load and Displacement Kit to record specimens and real-time test data, calculate results, then prepare reports following ASTM and AASHTO requirements.
• Sample Preparation products include the items needed to prepare soil samples for triaxial testing.
