Abstract
Methods of controlling the bulk density, permeability, moisture retention and thermal properties of bulk materials are provided by selectively sizing the bulk material. Preferably, the bulk material is sized into successively smaller particle size fractions, with the largest fraction placed into a confined area. The next smaller size fraction is then added until the largest sized fraction begins to dilate. The next successive smaller size fraction is added until the mixture beams to dilate, with the process being continued until the smallest size fraction is used. Methods of decreasing the density of bulk materials are also provided.
