Concrete strength testing
Concrete strength testing
(OP)
Are split or cone-split breaks more rare than for instance shear or cone breaks when testing concrete for unconfined compression strength? Any correlations between the break types and the type of pad used?





RE: Concrete strength testing
Since break patterns cannot be conveniently duplicated, it is tough to get correlations. You would have to review hundreds of test results of the same mix in order to get something like that, preferably by the same operator to get consistency of the break description.
