Ann: Positive Results from Concrete and Coatings Testing, page-90

Hey Wombat,

Your analysis here is priceless, could you throw your 2 cents in on this, 'standard' concrete specs have been around for ages, builders, industry, backyard handymen all know them...

32MPa, 40, 50, 65, 80, 100

A 1.5MPa batch variation is acceptable no concrete mob is going to change these standards to 33.5, 41.5,51.5 etc, and I don't foresee any engineers putting tighter tolerances on their spec. to force or narrow down suppliers of a specialised product.



Who is the end user here?


PS. Yes, I still hold, why? Because I still want to!
