What are reinfored concrete structures?
Reinforced concrete is a structural composite made of concrete, which is reinforced using multiple steel rebars or a single steel element called steel insert. Reinforced concrete is being formed into structural elements or entire monolitic objects using wooden-, steel- or plastic molds (formwork).
The connection of these two materials is being used in this way throughout the entire construction industry. Concrete is a material capable of handling high loads of compressive forces, although it is very weak regarding tensile forces.
On the other hand, the steel rebars in reinforced concrete elements are for managing mainly the tensile forces, although there are also often used compression reinforcements. Fusing steel and concrete together allows for the building of different types of structures.
The benefits of using reinforced concrete as a building material are:
-
fire resistance,
-
high stress-resistance against static- and dynamic loads,
-
freedom in shaping elements,
-
high corrosion resistance (if a proper cover of the steel inserts and a correct compaction of the concrete is being maintained).
Weather resistance can be upgraded by creating a relatively cost-efficient protective coating. These kind of protections are being used primarily in structures for bridges, overpasses and roof ceilings.
