Particle geometry of aggregate used in concrete is fully expressed in terms of three independent properties: form, angularity (or roundness), and surface texture. In this study the author proposed an evaluating method to integrate the three shape characteristics into a shape index using the specific surface area and mean particle diameter that are measured by the permeability test and the sieve analysis test, respectively. The shape index is able to include the surface texture of particles, and to evaluate the shape of mixed aggregate with fine and coarse aggregates.
