An Analysis of Factors Affecting Particle-Size Distribution of Hydraulic Cements



Particle-size distribution of hydraulic cements plays an indispensable role in controlling the product quality and maintaining reliable performance in end applications. Selection of particle-size measurement methods is becoming increasingly complex due to the availability of a variety of instruments based on different measurement principles. This paper discusses the primary criteria to be met by a particle-size distribution analzer for applications in hydraulic cement characterization. Among the several methods available for measuring the particle-size distribution, a light diffraction technique was utilized to examine the effect of dispersion solvents on the resulting size distribution. Distilled water, distilled water containing a polyacrylate surfactant, isopropyl alcohol, and a commercially available organic surfactant were used as dispersion solvents. The resulting data are analyzed with respect to variations due to the dispersion solvents and factors responsible for the observed variations.
