Content Summary | This study examines the influence of layer charge and smectite content on the rheological properties of mixed
bentonite–palygorskite suspensions. Eight bentonite samples containing smectite with layer charge ranging
between 0.38 and 0.54 e/huc were used to prepare 5% w/v mixed palygorskite–bentonite aqueous suspension
at pH 7. The influence of smectite on the apparent viscosity and yield point of palygorskite suspensions depends
on the proportion of the smectite in themixture and the layer charge and charge localization of the smectite. The
interaction between the two endmember clayminerals ismaximumat low percentage (10 to 20%) of bentonite
in the mixture. Low charge and high charge smectite tended to improve and deteriorate, respectively, the yield
point and apparent viscosity of the suspension. This behaviour seemed to be related to the influence of layer
charge of smectite on the degree of delamination and the thickness of smectite quasicrystals,which consequently
determine the number of particles involved in the interaction and the strength of particle–particle linkages. | en |
