Particle size distribution

This soil property is related to the liquefaction of saturated cohesionless soils as discussed in Section 5.2.2. As the test for its determination is a standard laboratory procedure, it

Although a number of classifications of grain size and standard sieves exist, correlations are straightforward, so that use of any scale of sizes can easily be applied in studies such as those for liquefaction potential.
