  • A digital image analysis of gravel aggregate using CT

    In this paper, the gravel aggregate of quartzite was studied by using the industrial CT instrument. MATLAB was used to capture the aggregate slice properties including reverse color, median filtering, noise reduction, binarization and so on. The 3D aggregate model was reconstructed by using the software of MIMICS.

  • Quartzite Parent Rock & Characteristics Britannica

    quartzite, sandstone that has been converted into a solid quartz rock. Unlike sandstones, quartzites are free from pores and have a smooth fracture; when struck, they break through, not around, the sand grains, producing a smooth surface instead of a rough and granular one. Conversion of sandstone to quartzite may be accomplished by precipitation of silica

  • The Complete Guide to Crushed Stone and Gravel grarock

    Crushed stone often has an angular and jagged edge that occurs during the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to the effects of running water. Quartzite: A metamorphic rock that is used in building blocks and slabs.
