Packing Density of Binary Mixtures of Wet Spheres

An experimental study of the packing of binary mixtures of coarse spheres with the addition of water has been conducted. The results indicate a similarity between dry and wet packings, either in the relationship between the packing density and the moisture content or in the relationship between the packing density and the particle-size distribution. The Westman equation is used to describe the wet packing after necessary modification. The approach is verified by the good agreement between the calculated and measured packing densities.
