Load Frame for Universal Compression Test of Rocks
Product Code : EL-RTLE-10509
Quick Answer: The Load Frame for Universal Compression Test of Rocks determines the unconfined compressive strength of intact rock core specimens by placing a machined, cut-to-length sample in a loading frame - heated to the desired test temperature if required - and continuously increasing the axial load until peak load and failure are obtained. It includes a 200 kN capacity, 12-speed load frame (0.0064 to 1.25 mm/min), a 200 kN proving ring with calibration certificate, a dial gauge with 25 mm travel and 0.01 mm least count, and can test AX, BX, NX rock specimens up to 100 mm.
This equipment is used for determining the unconfined compressive strength of intact rock core specimens. The rock sample is cut to length and the ends are machined flat, then the specimen is placed in a loading frame and, if required, heated to the desired test temperature. Axial load is continuously increased on the specimen until peak load and failure are obtained.
The equipment consists of the following replaceable parts:
Load frame, 200 kN capacity, 12 speed from 0.0064 to 1.25 mm/min
Proving ring, 200 kN with calibration certificate
Dial gauge 25 mm travel, 0.01 mm least count.
Horizontal clearance: 300 mm
Vertical clearance: 750 mm
Maximum platen diameter: 198 mm
Maximum platen travel: 100 mm
Platen set as per ASTM 2938 requirements
Specimen diameter: 38 mm to 100 mm
Can test AX, BX, NX rock specimens up to 100 mm
Standards: ASTM 2938
