Quite welcome, just remember that it is speculation combined with my
own experience. With that caveat in mind, I would say that cement is
not necessary as much as it is convenient. Any pozzolan (or many other
binders for that matter) could be used in it's place, but cement is
plentiful and not terribly expensive. Clay and other pozzolans can be
difficult to source or expensive, depending on your location. That is
not to say that the PC community is not open to the idea, as evidenced
by many other posters references to lime, clay, fly ash, Darjit, etc.
Best advice I have is what SG says alot, start small and do lots of
tests before you use it in something big. And always be safe. You can
mix up another batch if it goes bad, but growing back an extremity is
more difficult.
