US3909454A - Method for activation of bentonites -

A method for activation of bentonites is described. The method comprises a prior treatment of the bentonite with an organic polymer and/or an aqueous alkaline solution as known from prior art. Subsequently, an amount of 0.01 - 10% by weight from the treated bentonite of a heavy metal salt is incorporated into the pretreated bentonite and then dried at a temperature not higher than 400*C.

Wet tensile strength - GIESSEREILEXIKON.COM

It seems that a certain threshold is exceeded, above which the wet tensile strength falls sharply (level of 0.30 to 0.36 down to 0.17 N/cm2). Due to its low size, the wet tensile strength has a considerable influence on the formation of sand expansion defects in bentonite-bound mold materials (scabs, buckles, rat tails, veining and other defects).
