The Role of Dispersion in the Slaking of Intact Clay

Source

A series of slaking tests was conducted to identify those conditions under which dispersion is the dominant mechanism of clay slaking. Variables investigated were clay mineralogy, adsorbed cation ratios (sodium/calcium), consolidation fluid electrolyte concentration, water content, and slaking fluid electrolyte concentration.

All clays with sodium ions occupying more than 10 percent of the exchange complex exhibited a dispersion slaking regardless of other conditions, provided the electrolyte concentration of the slaking fluid was lower than 10−3 N.

Observed slaking behavior can be classified into four modes: (a) swelling slaking, (b) dispersion slaking, (c) surface slaking, and (d) body slaking.
