SAMPLING OF CONCRETE
Taking concrete samples at the point-of-placement rather than the point-of-delivery is always preferable. Special situations may occur which create difficulties in sampling and transporting samples taken from the point-of-placement. When this occurs, sampling at the point-of-delivery is satisfactory but only after running correlation tests between the 2 sampling locations. (Caution: The correction factors developed between the 2 sampling locations may vary due to changing conditions such as air and concrete temperature changes, pumping distances, etc. Perform correlation tests several times throughout the day.)
Now you can down load two manuals. Manual 1 is a little bit short like note, Manual 2 is more explanatory, you can download both manuals. just click in link given.
