GS interviewed by Alan Kohler, page-105

Virtually Edencrete trial appears to have been been cherry picked to make the product look good. EDE still haven't provided any independent economic data or Engineers Reports to back their claims.

GDOT could get standard 32MPa concrete from the local readymix for roughly half the price of using Edencrete. It would almost certainly perform as well - or better- than Edencrete at 4 gallons/yd3. [EDE haven't trialled Edencrete against other products of comparable performance - just very low strength standard mixes.]

If CNT admixtures was as good as claimed other admixture and concrete companies would be selling them. In reality Edencrete has almost zero sales outside Georgia and Colorado taxpayer funded trials.
