Measuring Particle Size Distribution of Gypsum Using Laser Diffraction
The performance of gypsum such as setting time, compressive strength or density deeply relies on its particle size distribution. Bettersizer ST, an analyzer for quality control, allows the measurement of particle size distribution of gypsum. In this note, two gypsum samples were rapidly and accurately measured with Bettersizer ST. Outstanding repeatability was presented subsequently by measurements of a ground sample, which indicates its excellent reliability.
