Abstract

This study presents some physical properties relevant to volcanic scoria powder characterization. Specific information on particle shape has been obtained using by 2-D images. The image analysis was used to identify key controls on particle morphology, six shape parameters: elongation, circularity, solidity, roughness, bluntness and luminance have effectively accounted for the morphological variance of powder particles. The particle shape is evaluated according to these six factors. These parameters are scaled to values between 0 and 1.0. Morphological changes associated with variations in the relative size and shape of particles have been quantified. According to results reporting by many authors, it is well known that particle shape analysis, which includes the full range of available grain sizes can contribute not only to the measurements of particle size and shape. But also in providing information on size-dependent densities, specific surface area by Blaine air permeability and specific surface area by laser diffraction.
