Rigid pipes, such as those made of concrete or clay, do not perceptibly flex when loaded and experience wall crushing when their load limit is reached. This mode of failure for rigid pipes has given rise to the terms "crush strength" and "D-Load", but these terms do not apply to PVC pipes.

The crushing strength of sewer pipes is determined by the three-edge bearing test. The pipe is stressed until failure occurs. Table (3) gives the minimum crushing strength for clay pipes. Strength requirements for reinforced concrete pipes are given in table 4, for this table the crushing force correspond to 0.25mm crack. The values in the table are pre mm diameter, that’s why they are

Circular concrete pipes are manufactured to Strength Class 120. This defines the minimum crushing load under test conditions and is equal to 120 multiplied by the nominal diameter (DN) of a pipe in metres. For example, a Class 120 concrete pipe of size DN600 has a minimum crushing strength of 120 X 600/1000 = 72kN/m. The test load is applied at

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.

The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.
