Reinforcements to reinforce concrete

Composite materials have been known since ancient times. Also concrete can enter into bonds with some materials and thereby significantly improve its already good properties. How Reinforcements Work in Concrete and What Types of Reinforcement Do You Can Read Here.

How Reinforcements Work

Concrete has a high compressive strength, but only a very low tensile strength. This is related to its internal structure. In order to compensate for this relative disadvantage, different materials can be arranged inside the concrete so that they absorb and thus neutralize the tensile forces impinging on the concrete component.

The resulting composite material is therefore also tensile and has offset its disadvantage. Each reinforcement requires that it is attached to the point where tensile forces can occur and that the structure of the reinforcement is sufficient to neutralize the impact forces on the component. It's all about:

  • a sufficient number of reinforcing elements
  • the correct arrangement of the reinforcement elements
  • the correct and sufficient connection of the reinforcement elements with each other, so that striking tensile forces can really be neutralized - otherwise the component would be damaged

reinforced concrete

Reinforced concrete is the best known form of reinforced concrete. In the concrete steel rods are embedded, which are interconnected by so-called spacers and other reinforcements.

Reinforced concrete is today the most widely and universally used building material for most components. The combination of steel and concrete has few weaknesses and is cheap and very effective to process. Especially in reinforced concrete skeleton construction today not only enormous cost reductions but also rapid construction progress are possible, as many mammoth projects prove.

Fiber-reinforced concrete

Concrete does not necessarily have to be reinforced with steel. Fiberboats also give the concrete more stability, they have a positive effect on the flexural strength of the brittle concrete.

In contrast, steel fiber reinforced concrete is a very cost-effective and fast alternative to conventional reinforced concrete in many areas. The building material is still relatively new, but is already spreading very fast.


Textile concrete is currently the most modern composite on the market. The reinforcement here consists of a textile fiber fabric, which does not corrode and can be optimally designed to absorb tensile forces. So extremely lightweight but highly durable concrete structures are possible.
