Abstract
The basic five types that need to be recognised are AA' active clay minerals, BB' inactive clay minerals, C fine cohesive primary minerals, D silt (at R approximately equals 1), E sand. We estimate that truly granular soils start at 200 microns and extend to 60 mm. We propose 60 mm as the upper limit of truly granular behaviour, which has been arbitrary chosen for the discussion purposes. From 50 to 200 microns we propose that a sixth definable sub-region type occurs, where R<1 but cohesive forces are still significant. We have tentatively defined three ideal collapsing soils: Soar Sand (at point E), Loughborough Loess (at D) and Quebec Quickclay (at C). These are defined in structural and mienralogical terms only, for the purposes of discussion. -from Authors
