Reinforced concrete - Wikipedia
Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.

Corrosion Protection of Steel Bridges
Corrosion is a serious threat to the long-term function and integrity of a steel bridge. Structural steel will corrode if left Because reinforced concrete and prestressed concrete bridges also employ steel more readily than concrete structures, steel bridges are inherently easier to inspect and maintain than concrete bridges.

Concrete Underground Homes
Concrete underground homes are one of the most proven ways to provide yourself and your family with a sustainable home that uses less energy from the electric grid. These structures usually use less water from main sources, as well.
Structural Engineering, Mechanics and Computation
A total of 18 reinforced and 12 partially prestressed concrete full-size beams have been tested in which measurements of crack spacing and crack widths at different load levels were made. Using the results from 4 reinforced and 4 partially prestressed concrete simply supported beams, the relationship among four governing parameters is established.
