Will Zeotech beat ADN to low-carbon concrete with its metakaolin?, page-25

it all comes down to cost, I doubt metakaolin is the only player here with similar characteristics but from what I’ve seen it’s not even the same postcode as using straight cement let alone flyash or slag ( or in the clinker process limestone ect )

admittedly I’m no expert on metakaolin seems interesting for niche high performance applications but you can also grind cement finer to achieve similar performance results ( Ie uhpc grouts ect )

probably similar to green nickel it’s a nice story but industry will continue to use the lowest cost option unless forced
