Cement Particle Size and Stability - HORIBA

Cement is made by heating limestone with small quantities of other materials such as clay or sand to 1450°C in a kiln. The resulting 'clinker', is then ground with a small amount of gypsum into a powder to make Portland cement. The most common use for Portland cement is in the production of concrete – a composite material consisting of cement, aggregate (gravel and sand) and water.
