With the increasing tendency of rock engineering applications to involve high temperatures, such as deep geological disposal of nuclear waste (Salama et al. 2015; Verma et al. 2015; Ye et al. 2016) and exploitation of geothermal resources (Sigurvinssona et al. 2007; Gelet et al. 2013; Zeng et al. 2013), research on the mechanical properties of rocks under/after exposure to high temperature has again attracted great attention. The rock material, a typical porous medium, contains original micro-holes and micro-cracks. Under hightemperature conditions, mineral thermal expansion and reactions occur in a rock, leading to variations in rock physical and mineralogical characteristics (Tian et al. 2012, 2013; Ozguven and Ozcelik 2014), and causing extension of the primary micro-cracks and development of new ones inside the rock body (Ferrero and Marini 2001). Consequently, the rock mechanical properties (eg, elastic modulus and uniaxial compressive strength) exhibit macroscopic variation with temperature, which has been verified experimentally through measurements of rock samples both under and after exposure to high-temperature conditions (eg, Ranjith et al. 2012; Brotóns et al. 2013; Yang et al. 2014; Zhang et al. 2016). Among the corresponding test results, extensive literature studies have been conducted on common igneous rocks such as granite (Heuze 1983; Dwivedi et al. 2008) and sedimentary rocks such as sandstone (Tian et al. 2012), providing interesting conclusions and guidance to scholars and engineers. Unfortunately, a similar literature study on metamorphic rocks has not been openly published in English. Marble is a widely distributed metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Its mechanical characteristics are mainly influenced by the original rock mineral composition and the environments experienced during metamorphic processes. In this study, an extensive review of Chinese publications, not considered in the English-speaking scientific community so far, covering the elastic modulus, uniaxial compressive strength, and peak strain of marble under/after exposure to high-temperature conditions and a generalized rule describing the effects of high temperature on marble are presented.
