How to define particle size?

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. In order to simplify the measurement process, it […]

Sample preparation by McCrone Micronizing mill before XRD/Rietveld test

In the cement science field, XRD analysis combined with Rietveld method can give quantitative results of crystalline phase of hydration products, so I try to use XRD/Rietveld method to quantify the hydration products of cementitous material. To achieve good performance of XRD test, fine powder is required and of great importance. The question is how […]
