Fiber Reinforced Plastics (FRP):Introduction-Properties

Fiber Reinforced Plastics (FRP):Introduction-Properties Concrete structures regardless of their purpose are disintegrating. A common link for this breakdown is that steel reinforcement is being used to strengthen the flexural capacity of the structures. Reinforcing steel will corrode when contact is made with humid or salty environments. When steel corrodes, it is expanding which creates tensile …
