These distinctions in soil are used in picking the soils to build structures on top. They were later refined by Arthur Casagrande. These limits were created by Albert Atterberg, a Swedish chemist.

Plastic Limit (PL) Roll clay until it breaks at 1/8 inch thick (3.2mm) 6. Theory The Atterberg limits can be used to distinguish between silt and clay, and it can distinguish between different types of silts and clays. Coarse-grained soils are highly porous in nature, whereas fine-grained soils have lower porosity. These limits were created by Albert Atterberg, a Swedish chemist and agronomist, in 1911. The water content at which soil changes from one state to the other is known as consistency limits, or Atterbergs limit.

Pre- dictable shear strength, low strain and consolidation characteristics, non-plastic behaviour, and better internal drainage make granular soils the superior wall building material. Atterberg limits (Holtz and Kovacs, 1981) LL PI H L Plasticity chart A-line separates clays from silts and the organics from the inorganics. In engineering practice, soils are classified as fine-grained (clay (<2 m) and silt (275 m)) soil and coarse-grained (sand (75 m -4.75 mm) and gravel (>4.75 mm)) soil based on the grain size distribution and Atterberg limits. The Atterberg limits can be used to distinguish between silt and clay and to distinguish between different types of silts and clays.
