I did the same ,asked around including my son in law who is a business development manager for a concreting company that has their own ready mix plant , none of them knew about Edencrete , you seem correct in that "most people in the concrete industry do not look at what new products are out there" .
Guess very few in the industry are prepared to risk a change or alternatively consider their current products are adequate .
Son in law was more concerned about something causing their concrete getting discoloured and homeowners getting upset about it .
