Abstract:
The effect of the hydroxyl-Al synthesis method on the hydraulic conductivity (HC) of a clay-sand mixture in the presence of hydroxy-Al was studied. Dispersion and transport of clay from the clay-sand mixture occurred only when the NaOH was added prior to Al(NO3)3 in the formation of hydroxy-Al precipitates. When Al(NO3)3 is added to the clay followed by NaOH, hydroxy-Al polymers interact with the clay particles to reduce swelling and dispersion. When clay and NaOH are mixed, followed by Al(NO3)3, precipitates form as a separate phase from the clay platelets. -from Authors
