Crush Testing
A crush test (more accurately a compressive strength test) is the way United Scanning usually answers this question. The compressive strength of a material, in this case concrete, is the ability of the material withstand or carry loads that would tend to compress it. United Scanning acquire a core sample of the concrete from the customer site

How Strong is PVC Pipe? (With PVC Strength Charts)
PVC pipe tensile strength can be measured by hanging weight from the pipe until it bends or cracks. As you can see from the chart to the right, tensile strength of PVC pipe increases as the size of the pipe increases. 8" PVC pipe of either schedule is extremely strong for how inexpensive it is. The smaller sizes are exponentially weaker, but

FAQ: How To Calculate Compressive Strength Of Concrete
For normal concrete and HSC, the concrete compressive strength test results from cube specimens are generally higher than cylinders specimens [6]. As states in BS 1881, the compressive strength of concrete gained by cylinder specimens is equal to 0.8 times of the compressive strength gained by cube specimens.

Recommendations for Design of Reinforced Concrete Pipe
The required strength of the concrete pipe is determined from the effects of the bending moment, thrust, and shear in the pipe wall. Wall thickness, concrete strength, and reinforcement design are evaluated using rational procedures based on strength and crack width limits that were developed in the ACPA long-range research program.

Concrete Pipe Crushing Strength. In the UK the minimum crushing load is usually specified as a multiple of the nominal pipe diameter. The most commonly specified strength class is 120, so the crushing strength in kN/m will be 120 times the nominal pipe diameter in metres.

Calculating crushing imposed by pipe supports
The basic answer is no you shouldn''t. The key issue isn''t a uniform "crushing" of the pipe, it''s the stress concentration and potential for denting and buckling at the end of the concrete pier. in many cases, the concrete itself can''t stand the edge load and breaks and spalls.
