Atterberg limits

In plastic soils, the water contents (determined by standard tests) which define the boundaries between the different states of consistency of plastic soils. Also see liquid limit, plastic limit, shrinkage limit.

Consistency limits (Atterberg limits) have been repeatedly shown to be useful indicators of clay behaviour (Jefferson and Rogers, 1998; Dolinar et al.
This paper was thus aimed at investigating the effect of seven surfactants (zwitterion, nonionic, anionic, and cationic surfactants) on smectite clay's consistency limits and contact angles.
Figures 3, 4, 5, 6, 7, 8 and 9 give the variation of modified clays' consistency limits by TMG, HEC, TRITON X-100 LABSA, SLES, CTAC, and QEFA, respectively.
It should be pointed out that there has been no general consensus regarding the effect of surfactants and chemicals on clays' consistency limits.
Consistency limits were significantly changed compared to those for natural clay.

The plastic limits are also called the Atterberg consistency limits in tribute to the work of Atterberg (1911).
McBride (1989) investigated consistency limits for 290 soil horizons with clay contents ranging from 5 to 94%, and presented mean water potentials of 694-1051 hPa for PL and 30-98 hPa for LL.
The Atterberg consistency limits of soils are used primarily in classifying cohesive soil materials for engineering purposes (e.
positive relationships between either clay or OM and the plastic limits, and a negative relationship between sand and the consistency limits.
Whereas the consistency limits (PL and LL) could be predicted from clay and OM, satisfactory prediction of PI required inclusion of an additional soil textural class (sand) in the regression model.
Moreover, McDonald's sheer size and its focus on restaurant-to-restaurant consistency limits the company's flexibility in adapting to changing demographics and consumer preferences.
