How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
The nature of ornamental stones is anisotropic. The heterogeneous characteristics of the anisotropic rocks vary with direction. The highest to lowest strength ratio is known as the anisotropy strength index (ASI). A thorough investigation of the ASI is necessary to determine the best-directed loads for these rocks. On core specimens that have been...
Decision-making is very important in many fields, such as mining engineering. In addition, there has been a growth of computer applications in all fields, especially mining operations. One of these application fields is mine design and the selection of suitable mining methods, and computer applications can help mine engineers to decide upon and cho...
Geological materials usually contaminated with naturally occurring radioactive materials (NORM) have become a focus of great attention. The radioactivity concentrations of 226Ra, 232Th and 40K in some ornamental stones in Egypt, were measured using a high-resolution gamma ray spectrometer. The natural radionuclide contents, (Ra) equivalent activiti...
A number of geotechnical analyses were carried out on selected samples from seven locations in Egypt. This was to assess the suitability of these rocks for ornamental uses. The analyses included uniaxial compressive strength, porosity, water absorption, hardness (SiO₂ content), resistance to abrasion and durability. Evaluation of these stones on th...
