Brazilian Test Apparatus
Product Code : JA-RT-9844
The Brazilian Test Apparatus (SKU JA-RT-9844) is a rock mechanics test set for determining the indirect tensile strength of rock by loading a disc-shaped specimen across its diameter. A pair of loading jaws contacts the disc at diametrically opposite surfaces over an arc of about 10 degrees at failure. The apparatus tests specimens of 50 to 100 mm diameter with a thickness of half the diameter; the jaws supplied suit 50 mm specimens. It is supplied by JaincoLab for civil, mining and geology laboratories.
Specifications
The set comprises a pair of loading jaws for 50 mm diameter discs (jaws for other diameters are ordered separately), for specimens from 50 to 100 mm diameter with thickness equal to half the diameter, and plain platens for cube and circular specimens up to 50 mm; the loading jack capacity are not listed in the product data and are confirmed on the quotation.

Applications of the Brazilian test apparatus
Students place a rock disc between the curved jaws, load it to failure along its diameter and calculate the indirect tensile strength from the failure load and disc dimensions.
- Indirect tensile strength of rock discs
- Comparing tensile strength of different rock types
- Specimen preparation to half-diameter thickness
- Rock mechanics practicals in civil and mining engineering
- Geology and engineering geology courses
