Interesting comparing those results. Do we know if the concrete mix was the same for each test?
If it were the same then it would seem you get what you pay for.
Also I suppose the different rates would also affect the amount of reo that could be saved on a particular job.
The amount of testing that has to be carried out to enable Eden to confidently guarantee that certain performances will be attained is mind boggling - especially if they ever start selling to Joe Blow the grano worker.
The disclaimer on the bottom of the tin would probably have to be quite extensive to cover all situations - type of cement, type of aggregate,slump,reo , etc and rates of EC to suit.
