Abstract

This study presents size and shape parameters relevant to volcanic scoria powder characterization. Particle size distribution was compared using two different techniques, including laser diffraction and automated static image analysis, and their respective results were discussed. Specific information on particle shape has been obtained using image analysis 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 effect of the number of particles of testing samples on these variables obtained through the image analysis was investigated. To develop analytical models, Multiple linear regressions analysis was applied using the dataset. The dataset comprised size and shape information’s about 24,268 particles from black natural powder, 32,302 particles from dark red natural powder, 22,562 particles from red natural powder and 25,041 particles from yellow natural powder. The analysis allowed us to identify the explanatory variables and develop eight mathematical models and three of these models are intended to prediction with very good significance. The correlation coefficients and analysis of variance test results obtained evidence the adequacy level of models. Thus, it is possible to estimate each dependent response parameter through the proposed models.
