Particle Size Analysis of Cement Using the Laser Diffraction Technique

The critical strength and curing properties of cement are dependent on the particle size distribution resulting from the grinding phase. In this application note, laser diffraction was used to measure particle size in samples of the raw mix and two cement blends using the Mastersizer 2000. It demonstrates that laser diffraction is a fast and effective technique for measuring the particle size of cement. Additionally, the broad size measuring range of the Mastersizer 2000 meant that the same lens could be used to measure particle size in the raw mix as well as extra fine cement grades.
