Ductile Iron pipe can withstand severe crushing loads. The ring test, shown above, determines a pipe ability to withstand load over a relatively small area, as would occur in rocky terrain where the pressure of a single rock, plus all the backfill above it, could cause weaker materials to fail.

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28

A concrete anchor is a steel shaft either cast into concrete at placement or post-installed after the concrete has hardened. Cast-in anchors are threaded shafts with a buried end termination of a hex head, threaded nut, or 90 (L-) or 180 (J-) hook, or headed (non-threaded) studs welded to a surface plate.

The concrete pipe crushing strength is not the only factor affecting the strength of the overall concrete pipe system. The bedding type has a significant impact as it has been demonstrated that the load carrying capacity of the concrete pipe is increased by the bedding by different amounts depending on the bedding type.
