Binder for clinoptilolite+bentonite mixture

[easypeasyac]

Hello;
I am trying to prepare granules from clinoptilolite+bentonite powder. I want to use it in soil so it must be moist and water proof and not loose their shape.

Some sources said that bentonite has binding capability and stand in water but all of my test are failed even pure bentonite granules.

I don't have chance for heat treatment so can't use heat require options. Binder has to be use in low level, and not too much increase soil ph and kh. What can i use for bind them?

Is acid treated sodium silicate possible?
