reinforced concrete (rc), also called reinforced cement concrete (rcc), 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 is usually embedded passively in the concrete before the concrete,reinforced concrete in construction, and preventing,without reinforcement, many concrete structures and buildings would not be possible. reinforced concrete is concrete that uses reinforcing steel bars ('rebars'), reinforcement grids, plates, steel tendons, fibers, or other material to increase its tensile strength. must meet the standards in the american concrete institute publication 347
