Plasticity clay
http://www.diva-portal.org/smash/get/diva2:1299954/FULLTEXT01.pdf Webb8.0 Definition of soil consistency. Soil consistency is the strength with which soil materials are held together or the resistance of soils to deformation and rupture. Soil consistency is measured for wet, moist and dry soil samples. For wet soils, it is expressed as both stickiness and plasticity, as defined below.

WebbClay as a soil component is inextricably linked to plasticity, extending beyond the ribbon test as a field measurement of soil texture. The modern understanding of soil mechanical behavior is explicitly linked to plasticity through a reliance on Atterberg limits. The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil: its shrinkage limit, plastic limit, and liquid limit. Depending on its water content, soil may appear in one of four states: solid, semi-solid, plastic and liquid. In each state, the consistency and behavior of soil are different, and … Visa mer Shrinkage limit The shrinkage limit (SL) is the water content where further loss of moisture will not result in more volume reduction. The test to determine the shrinkage limit is ASTM International D4943. … Visa mer The values of these limits are used in a number of ways. There is also a close relationship between the limits and properties of a soil such as compressibility, permeability, … Visa mer 1. ^ "Brief history of Swedish Soil Mechanics".
