LATERAL PRESSURE ASSEMBLY 10KG / cm² AZA0908
The AZA0908 Lateral Pressure Assembly (10 kg/cm²) from Azalab is a critical geotechnical laboratory accessory designed to apply and maintain uniform lateral (confining) pressure on soil specimens during triaxial shear and related tests. By accurately simulating in-situ stress conditions, this assembly ensures reliable determination of soil shear strength, deformation characteristics, and effective stress parameters.
The unit is primarily used with standard triaxial cells for UU, CU, and CD triaxial compression tests, making it indispensable for foundation design, slope stability analysis, and advanced soil research
Description
Principle of Operation
The AZA0908 operates by transmitting controlled air pressure to water inside a sealed pressure chamber. This water applies uniform lateral pressure around the triaxial cell, which in turn confines the soil specimen enclosed in a rubber membrane. A calibrated pressure gauge allows continuous monitoring and adjustment of the applied pressure throughout the test.
The system is designed for routine laboratory testing where stable confining pressure up to 10 kg/cm² (≈1000 kPa) is required.
