The validity of diametral compression as an effective means of determining the tensile strength of spherical ceramic bodies has often been questioned. In this paper, a comprehensive review of the original work, as well as alternative studies that suggest shortcomings of the original method, is made. For comparative purposes, data recently collected via diametral compression on aluminosilicate aggregates is presented in the context of these latter works and compared with the original methodology. Overall, results indicate that the diametral compression test can indeed provide an accurate measure of tensile strength when several important test criteria are met.
