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.

To accommodate our customers’ varying needs and budgets, we offer a wide range of testing equipment:

Standard testing equipment:

Automatic testing equipment:

  •  Autotriax EmS: the most flexible automatic triaxial testing system that can perform up to 6 entire and independent tests at the same time; composed of different components that can be combined for covering all the requirements.
  • AutotriaxQube: Revolutionary all-in-one automatic triaxial testing system integrating the many components of triaxial testing into one, single compact system.

 

In order to configure each triaxial test accordingly,  CONTROLS and Wykeham Farrance offer a variety of components:

 

1. Load frames are used for applying vertical force in triaxial testing. Six models of load frames are available depending on the maximum capacity and whether they are fitted with a built-in data acquisition.

2. Triaxial Cells are the main element for triaxial testing and consists in chambers with a variety of sizes where the prepared specimens are mounted. Each model comes in several versions with different dimensions and pressure capacities.

3. Pressure Systems are typically used to generate cell pressure and back pressure during testing.

4. Data acquisition is used to obtain, display in real-time and store data in Standard Triaxial equipment, as well as control and manage all the devices in Automatic triaxial equipment.

5. De-airing systems work with a vacuum source to remove trapped air from water supplies for triaxial and permeability tests. We offer two types of de-airing water systems: the standard de-airing water system and the top of the range standalone de-airing all-in-one water system.

6. Measurement Components: There are three primary groups of measurement components: analogue, electronic, and advanced electronic.
