What are reinforced concrete structures?
Reinforced concrete is a composite structural material consisting of concrete strengthened with steel reinforcement bars or a single steel element, known as a steel insert.
Reinforced concrete is formed into structural elements or monolithic structures using wooden, steel, or plastic formwork (shuttering). This combination of concrete and steel is widely used in construction.
Concrete is a material capable of withstanding high compressive stresses, but its tensile strength is low. Steel reinforcement in reinforced concrete elements primarily carries tensile stresses, although compression reinforcement is also frequently used. The combination of steel and concrete allows for the construction of various types of structures.
The advantages of reinforced concrete as a construction material include:
- Fire resistance,
- Ability to withstand high static and dynamic loads,
- Flexibility in shaping structural elements,
- High corrosion resistance (with proper concrete cover and adequate compaction of the concrete mix).
Resistance to atmospheric influences can be enhanced through cost-effective protective coatings. These coatings are primarily applied to bridges, overpasses, and roof slabs, improving durability and reducing maintenance needs.
