Some Mechanical and Physical Studies of Granitic Rocks in Um Taghir, Eastern Desert, Egypt

Granitic rock is considered one of the most important economic materials used as building materials, ornamental stones, and other purposes. According to previous radiological studies conducted on these granites, it was found that the activity concentrations of ²³⁸U, ²³² Th and ⁴⁰ K of these granitic rocks are natural as well as the radiation effects are not harmful due to the natural radioactivity of the examined granites so that it can be exploited economically in the future.The current study aims to determine some of the physical and mechanical properties of granites in the Um Taghir area to detect these rocks' suitability for ornamental stones. The samples of the granitic rocks were cut according to the American Society for Testing and Materials specifications (cubic shape) for the detection of uniaxial compressive strength in addition to some of the physical properties were determined for each sample. Granite rock samples showed good results according to mechanical and physical tests. So that it can be extracted, transported and later used for various economic purposes. (paper)
