Trade Journals for the Concrete Industry

In the production of round concrete parts (e.g. sewer pipe systems), steel reinforcements are placed into the mould. Concrete is known to be very pressure resistant but in no way tensile or bending resistant. Depending on the installation position different areas of tension arise, which have to be supported differently by steel reinforcements. The best reinforcement cage, by theory, would start with a round shape to support the area of pipe, which is connected with the next pipe, go on with an oval geometry for the middle of the pipe and end with a round shape again, for the second connection end.
