Particle size | Cement Science
Particle size is a very important property in the research field of cementitious materials, e.g. modeling, reaction kinetics. Particles are 3-dimensional objects, and unless they are perfect spheres, e.g. emulsions or bubbles, they cannot be fully described by a single dimension such as a radius or diameter.
