Hi Jim, I'm kind of rusty on the subject, and was hoping to be flooded with some current data, but the responses so far have been weak. Well, I had read the book many years ago and tried a number of experiments. My notes, on the computer, died a couple of computer crashes ago. I still have some hand written notes, but they are currently in storage. I'll dig them out. In the mean time I looked around on the net and found a few references. http://www.ferrocement.net/archives/msg10857.html for instance has some notes by Davidovits himself, and a lot of ornamental casting info appears on http://www.makersgallery.com/concrete/howto.html and connected pages. Pretty thrilling to think about, some of it.
Thanks for your response! Edley. o: <[EMAIL PROTECTED]> Subject: Cast stone formulas Date sent: Thu, 31 Oct 2002 07:27:41 -0500 From: <[EMAIL PROTECTED]> Hi Edley, I was very interested in your last posting to the SML, dealing with the book about cast stone. I have experimented in that area and was interested to learn a bit more about the book that you mentioned. Could you shed a bit more light on some of the formulas that you mentioned? Which ones did you try and how did they work out? I have come up with a special mix of concrete (although by strict definition I could probably call it "cast stone" since it contains crushed stone particles which are "reconstituted" - held together in a portland matrix) for the base of my Spectra sundial. I am currently working on some new projects that could also benefit from any special mixes you could point me toward. I am familiar with the subject and look forward to hearing more...I would like to try a few of them myself! Jim Tallman -
