“…8 Compressive strength of granites as a function of temperature reaches a peak at 300 °C; at higher temperatures it starts to decrease strongly. Similar facts were presented by Heuze (1983). Up to 300 °C the measured samples show a decreasing Young's modulus, and above that temperature, at 600 °C, the values dropped dramatically.…”

“…These include thermal cracking, changing of color and also a loss in strength or complete disintegration of the fabric (Heuze 1983). In case of fire it often leads to the collapse of buildings (Russo and Sciarretta 2013) or endangers tunnels.…”

“…The specimens were heated under laboratory conditions; physical properties such as density, ultrasonic pulse velocity, tensile strength and uniaxial compressive strength data were recorded. The results were evaluated and compared to the dataset of previous publications such as Heuze (1983) and Dwivedi et al (2008).…”

The paper provides information on the mechanical properties of granitic rocks that were subjected to heat. Two types of granitic rocks were tested under laboratory conditions at temperatures of 23 °C, 300 °C and 600 °C. The granitic rock from Bátaapáti (Mórágy Granite) is a pinkish leucocratic monzogranitic type while the second type is grey granite from Mauthausen (Austria). The samples were placed in furnace and temperature raised to 300 °C. Other set of samples were heated to 600 °C. Mechanical tests were performed on non-heated and heated samples and the test results were compared. Heating to 300 °C caused a slight increase in the uniaxial compressive strength and in indirect tensile strength, with reference to the samples kept at 23 °C. A drastic drop in both values was observed when samples were heated to 600 °C. The density of the samples did not show a major change up to 300 °C. On the contrary, a decrease in ultrasonic pulse velocity was observed, with an additional significant loss when samples subjected to 600 °C were compared to the reference samples of 23 °C. This decrease can be related to the initiation of micro-cracks. With increasing temperature the Young modulus of both granites was reduced.

“…Temperature dependent mechanical parameters such as strength, elastic modulus and Poisson's ratio are the basic parameters relevant to deep underground excavation support design and stability analyses. Hence, the impact of high temperatures on rocks is considered as an important topic in rock mechanics.The deformation mechanisms and failure criteria of different types of rocks at high temperatures has been studied by various researchers (Stesky et al 1974;Heuze 1983;Rao et al 2007;Wan et al 2009;Zhang et al 2009;Chen et al 2012;Ranjith et al 2012;Brot-ns et al 2013;Wu et al 2013;Liu et al 2013;Zhang et al 2014) and it has generally been shown that high temperature has a significant effect on the mechanical properties of rocks. However, the extent of the effect has been shown to vary for different types of rock, depending on factors such as mineral composition, porosity, density, and presence of cracks.…”

This paper presents results from tests performed on samples of sandstone treated to a range of temperatures between 20 and 1000°C. Sandstone samples obtained from underground coal gasification (UCG) trial sites in Poland were selected for the tests. Multistage triaxial tests were used to determine the mechanical properties of the samples.X-ray diffraction (XRD) and thermal analyses (TA) were performed to investigate the changes in the physical and chemical properties of the samples under increasing temperature. Micro-computed gomography analyses were carried out on selected samples in order to reveal the microstructural changes that take place as a result of the heating process. 3D characterization of the sample porosity and pore size distribution were performed to obtain a quantitative comparison between samples subjected to different temperature treatments. The relationship between micro-structure and macro-mechanical characteristics of sandstone at high temperature is discussed. The results illustrate that the mechanical properties of sandstone are closely related to alterations of microstructure that result from increased temperatures. IntroductionThe effect of high temperature on the thermo-mechanical response of rocks is important for several engineering applications, including underground nuclear waste storage, geothermal energy resource exploration, and underground coal gasification (UCG). Generally, the scope of high temperature ranges from normal temperatures (10-50 ¡C) to extreme temperatures (1000-1500 ¡C). Under the influence of high temperatures, the mechanical properties o...
