Ann: Appointment of Corporate Advisor, page-46

Quoting James from the CRUX interview:

"So the concrete testing is something i've been involved with now for over 30 years various forms of kaolin that go into concrete and it is used as an additive for various reasons around the world so something i'm quite used to ​

​

I've been involved in pattern working concrete and all sorts of other concrete testing activities so when I saw the structure of the halloysite the charge structure that and the shape of the particles i realized that there was a good potential for some positive interaction which used in a concrete so knowing that chemical basis on a morphological basis then i spent a long time making up various mixed designs just to see what the potential benefits could could be and after a lot of sort of backyard bucket testing of this material realise that yeah this this has got true potential.​

​

At that point used a very experienced consultant concrete consultant to set up a very thorough testing program."​
