Abstract EN
Dispersive soils are characterized by three features: (1) unstable structure, (2) theyare readily flocculate in water, and (3) very erodible.
The use of dispersed claysoils in hydraulic structures, dams and road dams can cause serious engineeringproblems when this soil is not identified and used befittingly.
There is a simpleway to determine soil dispersion and more difficult to measure dispersion.
(Atterberg'slimits) (grain size analysis), and (visible classification) are not enoughto recognize between (normal clays) and (dispersive clays).
ASTM tests canidentify dispersive clay, these include: (double hydrometer test), (chemical tests), (Crumb test), and (Pinhole test).
In this paper, the dispersed soil has beenartificially prepared by adding Na2CO3 to natural clay in different proportions.
The proportions are 5% , 15% , 25% , 30% , 35% , and 40% by weight.
The target ofthis investigation is to investigate the effect of degree of dispersion of the soil onAtterberg limits.
The study showed that the percentage of dispersion increaseswith Atterberg'slimits and the dispersion ratio and the plasticity index relationshipare related by a direct very erodible.
