Not worth the airfare . Ask Alexander to table the real deal with Descrete (Dont accept the confidentiality bla bla ). Who is Jean Defosses or Jean Desfosses the inventor of the Australian patent applications - who is he and what are his credentials - or is it a nom de plume !!! - what are the real costs to produce 1 ton of calcine clay at SR and 1 ton of hydrous clay at SR ; what is the freight cost to : China , Sydney , Melbourne, USA , Indo ? What is the selling cost of the green wonder admixture - incl all chemicals. Ask him to validate every cost in writing to the AGM .Compare this to 1 ton of OPC and similar Blast Furnace Slag binder admixtures on the market currently.
Dont accept Alexanders waffles and pleading confidentiality.
