Ann: EdenCrete - US Update, page-30

You are assuming there are competitive issues from other admix suppliers, my counter assumption was that edencrete was competing more with the cement reinforcement ie mesh and rebar and which will be not needed at all or in smaller quantities per cubic yard of cement poured.
The other material that may not be needed in as high a concentration is cement itself , is maybe a 7/1 aggregate/cement mix with edencrete will suffice where previously a 5/1 mix is needed
I doubt if fly ash would be a competitor as I feel it probably does not impart any of the advantages edencrete has it looks more a replacement for the smaller sand fraction of the aggregate found in builders mix , but maybe there are other product admixers/ hardeners I am not aware of .
