What is the purpose of using metal bars or mesh in the construction of concrete roads?
Concrete, while strong under compressive forces is very weak under stretching forces. Metal bars or mesh, while strong under stretching forces is very weak under compressive forces. Thus they compliment and mutually reinforce each other: where one is weak the other is strong.To make sure they are both able to work their best, the metal bars or mesh are first stretched then the concrete is pored over them. When the concrete completes setting the metal bars or mesh are released and they now compress the concrete while the concrete keeps them stretched. This is called prestressed concreteand it is much stronger than ordinary concrete.
