A series of experiments was performed on glass beads and natural clean dry sands under the objective of the current work of performing parametric studies. Therefore, new techniques and methods were utilized to predict the gradation of the natural cohesionless silica sands tested in addition to the conventional geotechnical laboratory experiments, which were carried out to predict the mechanical characteristics of such soils. Moreover, ideal laboratory simulations for the SPT were performed under several particular relative densities, loading conditions, and stress-strain controlled boundaries. Additionally, the obtained results from such series of experiments were stored in digital forms for further processing and analyses. 2.1. The…show more content…
Furthermore, the angular scattering intensity data were then analyzed to calculate the sizes of the particles that created the scattering pattern for the particle size was reported as a volume equivalent sphere diameter. Such process of subjecting a laser beam and the analysis of the laser diffraction was repeated ten times, by default of the scanner, during each testing cycle to improve the accuracy of the results. Moreover, the results, which were found to have inconsistency were neglected (e.g., large particles soaked down and escaped from the laser beam or overlap between two adjacent particles during the laser diffraction). Finally, by experimenting the three specimens for the six samples (a total of eighteen specimens), the grading curve of the tested soil was developed based on the volume of the individual particles. On the other hand, a light stereomicroscope (Leica MZFL-III fluorescence stereo-zoom microscope), presented in Figure 5, was employed for the image analysis to develop the grading curves of the sands having particle’s diameters more than 2.0 (mm). Additionally, the two-dimensional angularities of all the natural sand samples, tested in the current work, were also predicted using the obtained two-dimensional images. In fact, the image analysis is a two-dimensional analysis; hence it is less accurate than the
