The nature and properties of such layers are highly dependent on the type of mineral and –the chemistry of the pore water. Adsorbed Water (Stern Layer) • The innermost layer of doublelayer water which is held very strongly by clay is known as adsorbed water (Stern layer). • This water is more viscous than is free water.

Mixture of deflocculants A systematic approach
Jan 01 2007 · The deflocculants show a different effect on the rheology of the illitic-kaolinitic clay with respect to the kaolinitic clay as it is observable in Fig. 4 and Eqs. (4) (5) (6) . In general for all the samples the rheological behaviour is shear thinning with low yield point.

(PDF) Obtention of highly dispersed platelet-reinforced
Highly homogeneous mixtures of alumina/platelets with different platelets content (5 8 12 and 20 vol ) have been obtained by controlled flocculation at a pH value in the range 6-7. From these powders very close to theoretical density ( >/99 dth) and slightly oriented platelet-reinforced alumina compacts have been obtained by hot pressing

The synergistic effect of adding a blend of deflocculants
Jan 10 2020 · The properties of aluminate cement-based high temperature resistant concrete with MS addition can be greatly improved by using a blend of deflocculants that due to combined good rheological properties almost double the increase in compressive strength of a concrete compared to a concrete prepared with only one of the deflocculants.
