Webb30 juni 2024 · Minimum Void Ratio of Each Particle Group. We classify three types of natural sand (i.e., DS, NS, and FS) into five particle groups: 0.1 to 0.25 mm, 0.25 to 0.5 mm, 0.5 to 1 mm, 1 to 2 mm, and 2 to 5 mm particle groups. Among them, the number of particles of 2 to 5 mm in FS is very small, which is difficult to obtain.
