Cement particle size analysis

The measurement and control of particle size distribution in cement are very important for both the desired product composition and controlling production costs. Conventional methods, such as measuring the particle size distribution by sieving and determining fineness according to the Blaine air permeability method, are still in use, but laser diffraction becomes increasingly popular for determining the distribution of cement particles by size. Application of laser diffraction yields quick and easily reproducible results and gives a complete picture of the particle size distribution. This article describes the laser diffraction particle size analyzers from the Japanese company HORIBA together with their characteristics.
