Unconfined Compression Testing Machine (UCTM) is used to determine the unconfined compressive strength (UCS) of cohesive soils, typically clay. It is one of the simplest forms of compression tests and is widely used in geotechnical engineering.
The machine applies axial compression load to a cylindrical soil specimen without any lateral support until it fails in shear. The maximum axial load at failure is used to calculate UCS.
| Type of Soil Tested | Saturated, cohesive soil (clay, silt with clay) |
| Sample Size | 38 mm diameter × 76 mm height (standard); others as per requirement |
| Loading Frame Capacity | 50 kN (manual or motorized) |
| Loading Rate | 1.25 mm/min to 1.5 mm/min or 2.5 mm/min |
| Displacement Measurement | Dial Gauge (0.01 mm least count) or LVDT for digital systems |
| Load Measurement | Proving ring (manual) or Load Cell (digital) |
| Data Output | Analog scale or digital display (USB/RS232 interface for PC-based models) |
| Power Supply (for motorized type) | 230V AC, 50 Hz, Single Phase |
