Analysing the Particle Size of Cement via Laser Diffraction

Malvern Instruments

The cement production process is typically made up of three distinct stages: preparing the raw mix, producing the clinker, and then grinding the clinker to form the finished cement.

The critical strength and curing properties of cement are dependent on the particle size distribution resulting from the grinding phase, as compressive strength and curing qualities are increased as the particle size decreases due to the increase in surface area.

The particle size distributions of the various cement samples have been measured by laser diffraction using a Mastersizer 2000; laser diffraction instruments operate by illuminating particles in a collimated laser beam and measuring the scattered light over a range of angles.
