DESCRIPTION

The Fredlund SWCC Device is a simple unsaturated soil testing apparatus with great flexibility for applying matric suctions while following various stress paths.

The device can be used to obtain the complete soil-water characteristic curve (SWCC) for a soil. The Fredlund SWCC Device allows you to control matric suctions from near zero values up to 1500 kPa (i.e., 15 bars), and is capable of applying one-dimensional loading, Ko, to a specimen with a diameter up to 75 mm. The device is economically priced and is a complete ‘turn-key’ system.

The cell is constructed of stainless steel and includes the necessary plumbing and valves for periodic flushing and measuring of diffused air. Several different high-air-entry-value (HAVE) ceramic stones can be easily interchanged. An optional pneumatic load frame loader is available to apply larger normal pressures.

Through its convenient design, the apparatus allows the use of a single soil specimen to obtain the entire SWCC with any number of data points.
