Crushing strength | geology | Britannica
In compressive strength test. The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch.

Why Concrete Pipe?
Since Concrete pipe is a rigid pipe system that is over 85% dependent on the pipe 7strength and only 15% dependent on the strength derived from the soil envelope, installation is made easy. In many situations, the installation of plastic or metal pipes can take longer than precast concrete pipe.

Frequently Asked Questions about Advanced Drainage Systems
A HDPE pipe profile can actually deflect until the material is flattened due to reverse curvature. Therefore, an analogous test to crush strength for HDPE pipes would be AASHTO's pipe flattening test, which requires the pipe be deflected 20% with no signs of wall buckling, cracking, splitting, or delamination at a specified pipe stiffness.
