摘要：To develop high-performance and versatile cement-based materials like self-compacting concrete SCC and reactive powder concrete RPC, the research on inert and semi-inert powders from natural resources has been increased. In this study, the particle shape and surface morphology of powders from volcanic scoria VS (Black, Dark-Red, Red and Yellow) collected in Cameroon has been analysed. Four powders were prepared by grinding with the same energy for all. Particle size distribution PSD were performed by using laser diffraction LD. Blaine fineness BF of powders were performed. Shape, surface morphology parameters and image analysis IA of these fine materials were performed. Shape characteristics of theses powders were presented and were correlated with Blaine fineness.In addition to PSD, granulo-morphology has been providing a better understanding of particle shape and surface morphology parameters and their influence on blended cement.
