EDE Chart, page-149

I'm no concrete expert but reading the info on each, I make the following observations;

Edencrete is a simple add mixture, the Super Crete system isn't.

Edencrete is a low net cost system, not sure about Super Crete.

Edencrete appears to have significant positives such as minimal shrinkage, reduction in reinforcing, improved resistance to water ingress causing rust staining, concrete cancer. Can't see how the steel fibre aspect of Supercrete is being dealt with re above. Am only a mug punter (and TAS SH) though.
