found an epoxy supplier that claims 1 to 5 ratio by volume possible with sand filler.If true this would reduce my previous cost estimate by almost 50%.Cost at this ratio would be $6.00/sqft 1" thick.Never beleive what you read.To confirm stats I would buy 1qt resin add 5qt sand and see if it can be mixed.I really don' twant to give the supplier link as it is the most confusing site I have ever seen.
AW what the hell you gotta see this,5billion pages and links.Don't try their search engine.www.epoxysystems.com.
Glad to see interest in the subject.Don't go out and buy a ton of epoxy and sand yet.There is still alot of issues to be dealt with.eg air entraptment ,vibratory compaction, heat generation,viscosity , vacuum de gassing etc.I wish I had the time to do the experiments now so It was my risk only.I only have experince with 50% fill by weight.Some sites have stated 90% filler.I don't know.At this level it ain't gonna be a pouring item.As I said before I have tons of orders now and little time.working 18/7.I have tons more info to post.Questions or comments are welcomed.Try to keep the interest happining.
