What is a key feature of a reinforced concrete's mechanical properties?

• A. Higher ductility than steel
• B. Lower strength than normal concrete
• C. Combination of compressive strength and tensile resistance
• D. Inability to resist tension

Answer: (C)

The key feature of reinforced concrete's mechanical properties lies in its combination of compressive strength and tensile resistance. Concrete on its own is very strong in compression but weak in tension. To address this limitation, steel reinforcement is incorporated within the concrete. This integration allows the material to effectively withstand both compressive forces and tensile stresses. The steel reinforcement flexibly carries the tensile loads, which enhances the overall durability and structural integrity of the concrete. This synergistic relationship between concrete and steel is what makes reinforced concrete widely used in construction, particularly in applications where a combination of these mechanical properties is required.
