Great post Pat. Yes I read it all, and you left me still hungry for
more info. Well done. Please keep us posted.
I think with my long diatribes putting everyone to sleep, an
occasional long post from you will be a breath of fresh air to
everyone. Keep it up. :) hehehe
I'm sure that I used cement in my sample. I can't recall if I would
have used clay, flyash, and/or sand. I would have had all those
ingredients on hand at the time I did it (several years ago). Your
use of lime make sense to me. It ought to make the mix more sticky
and "gluey" helping the slurry hold together better. I doubt I would
have had any lime in my samples.
I find myself wondering about taking waste cedar from old fences or
whatnot and chopping/grinding it up. It might make a fantastic
plaster for the inside of closets. A budget cedar closet! Should
smell great too.
