Description
Why Rock Compression Testing is Important
Rock compression testing determines the maximum axial stress that a rock sample can withstand before failure. This data is essential for:
-
Foundation and footing design
-
Tunnel and underground support planning
-
Slope stability and landslide assessment
-
Dam and hydropower project safety analysis
-
Seismic and rock fracture behavior studies
AZA1007 enables engineers to obtain these critical parameters with high accuracy.
Working Principle
The machine operates using a vertical compression system where cylindrical rock core specimens (typically Ø50–100 mm) are placed between hardened steel platens. A hydraulic or mechanically driven system applies a steadily increasing compressive load.
The 12-speed gearbox allows operators to adjust loading rates based on rock type and testing standards. A calibrated load indicator displays force in real time, while optional digital systems can record stress–strain curves for advanced analysis.
