Abstract

Elevated temperature causes changes in mechanical properties of rock, due to thermal effect and mineralogical transformations, which show great varieties for different lithologies. The present paper provides information on seven different sandstones. The studied predominantly quartz sandstones show different petrology from fine-grained to coarse-grained with silica, carbonate and clayey cement. The changes in rigidity as a function of temperature were documented. The analyzed data set includes the uniaxial compressive strength and indirect tensile strength measured at 22C, 150C, 300C, 450C, 600C, 750C and at 900C, respectively. The test results allowed determining the changes in rigidity. Brinke number was also calculated and clearly show a trend with increasing temperature. The Brinke number of the studied sandstones was in the range of 5-20, showing the higher values at higher temperatures. Constants were calculated for equations describing the trends in changes of rigidity. Our results indicate that the rigidity of sandstone depend on thermal conditions and show different rate of changes depending on the micro-fabric and petrological characteristics of sandstone.
