High-Temperature Brazilian Test for Tensile Strength of Metamorphic Limestone



This technical note presents a low-cost and fast, high-temperature tensile strength test of rocks. A series of splitting tensile strength tests, the so-called Brazilian test, were conducted on metamorphic limestone specimens at high temperature using a special triaxial cell assembly that can sustain a maximum temperature of 315°C. Results of these Brazilian tests at various temperatures (30, 100, 200, and 300°C) are presented and discussed. The results show that the tensile strength of the rock decreases as the temperature of the rock increases. The reduction in tensile strength is found to be greater when the tests are actually conducted at high temperature rather than at room temperature using thermally treated specimens.
