a rock is determined indirectly by means of a test better known as the Brazilian test. The Brazilian test for rocks is regulated by ASTM D3967: this test allows to indirectly evaluate the tensile strength of a rock starting from the crushing of a specimen. The indirect tensile test is a quick test that allows a quick assessment of the toughness of a rock.<\/p><p>The Brazilian test for rocks consists in squeezing a rock specimen between two concave jaws: starting from the value of the force applied to reach the failure of the specimen, the tensile strength of the rock is ascertained.<\/p><p>According to ASTM D3967, the rock specimen to be subjected to the Brazilian test must have specific characteristics: it must be a circular disc in which the ratio between thickness and diameter must fall within the range 0.2-0.75. In general, the diameter of the specimen must always be at least ten times greater than the largest grain of the rock. To have a significant value of tensile strength it is advisable to perform the test on several specimens, in order to mediate the results as a function of the intrinsic anisotropy of the rock: the more homogeneous a rock is, the less tests will be required. The tensile strength by the Brazilian test is determined by inserting the rock specimen between two curved jaws, which distribute a load to the specimen which is applied to them via two plates. LRRT owns a Brazilian GCTS test rig like the one in the figure below.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-dea706e elementor-widget elementor-widget-image\" data-id=\"dea706e\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.5.2 - 22-12-2021 *\/\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"780\" height=\"559\" src=\"\/\/www.w3.org\/2000\/svg&#039; viewBox=&#039;0 0  &#039;%3E%3C\/svg%3E\" class=\"attachment-large size-large ld-lazyload\" alt=\"\" data-src=\"https:\/\/tononeng.com\/tonon-usa\/wp-content\/uploads\/2022\/02\/brazilian_tensile_apparatus-1024x734.jpg\" data-srcset=\"https:\/\/tononeng.com\/tonon-usa\/wp-content\/uploads\/2022\/02\/brazilian_tensile_apparatus-1024x734.jpg 1024w, https:\/\/tononeng.com\/tonon-usa\/wp-content\/uploads\/2022\/02\/brazilian_tensile_apparatus-300x215.jpg 300w, https:\/\/tononeng.com\/tonon-usa\/wp-content\/uploads\/2022\/02\/brazilian_tensile_apparatus.jpg 1132w\" data-sizes=\"(max-width: 780px) 100vw, 780px\" data-aspect=\"\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Apparatus for the Brazilian indirect tensile test supplied to the Rock and Research Laboratory Tonon srl.
