It would be interesting to see what the cost of the EDE additive per volume of concrete.

My brief read of info on their web site tells me the additive product is a carbon nanotube of some sort. No indication of price though. The pitch suggests it’s like adding carbon fibre to concrete. Sounds good but I’m betting it’s not particularly cheap.

At face value, ADN’s additive is likely to be a much simpler and cost-effective solution, as the kaolin additive needs to
be quarried then undergo only minimal refinement prior to use, if my memory serves me.
