LBTC-230 Rock Splitting Tensile Strength Fixture

Description

Product Introduction:

The rock splitting‑test fixture is used to determine the tensile strength of coal and rock and is suitable for coal and rock that can be prepared into standard test specimens. A radial compressive line load is applied to solid cylindrical specimens until failure, thereby determining the specimen’s tensile stress. It complies with the requirements of GB/T 50266 “Standard for Test Methods of Engineering Rock Masses” and GB/T 23561.10 “Methods for Determining the Physical and Mechanical Properties of Coal and Rock—Part 10: Method for Determining the Tensile Strength of Coal and Rock.”

Technical Specifications:

Material: Steel

1. Specimen specifications: Standard specimens shall be cylindrical, with a diameter of 48–54 mm and a thickness equal to 0.25–0.75 times the diameter. The particles within the specimen shall be smaller than one-tenth of the diameter.

2. Number of specimens: The number of coal or rock specimens from the same layer shall be no fewer than five.

3. External dimensions: 122 × 60 × 190 mm (length × width × height)

4. Outer carton dimensions: 212 × 110 × 225 mm

5. Weight: 5.7 kg
