Durability of reinforced concrete structures
WebReinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and … WebJun 11, 2024 · Method: A spring release mechanism is used to activate a hammer which impacts a plunger to drive into the surface of the concrete.
