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.

Concrete crushing after yielding of steel reinforcement represents an under-reinforced member, which is typical of current reinforced concrete design standards. This failure mode ensures that a high level of member ductility is maintained prior to failure, thus providing ample warning before collapse. In the case of FRP-strengthened members

The most common method for monitoring the strength of in-situ concrete is the use of field-cured cylinders. This practice has remained generally unchanged since the early 19 th century. These samples are casted and cured according to ASTM C31 and tested for compressive strength by a third-party lab at various stages.
