What is Adherence?

Reinforced concrete is the main structural material used in the construction of bridges, roads and commercial and residential buildings. In reinforced concrete, which means reinforced concrete, the main event is the use of concrete and reinforcement together, and this combination is based on the adhesion of two types to each other. This adhesion is called adherence.

Adherence is the most important property of reinforced concrete to which it owes its existence. When there is no adherence, it is out of question to talk about reinforced concrete.

In order for a structural element made of concrete and steel rods to act as reinforced concrete, the rods must be clamped to the concrete. This interlocking; It is affected by many variables such as the tensile strength of concrete, yield strength of steel, surface geometry of the bar, reinforcement diameter, clamping length, concrete cover thickness around the reinforcement, type of aggregate used and additives.

The first pioneers of high-strength steels in the field of application were those with round and flat types, with adherence properties not much different from soft reinforced concrete reinforcements. However, after a while, it was understood that in order to benefit from the high performance of these new types of steels, it was understood that it was necessary to increase the interlocking with the concrete, and modern reinforced concrete reinforcement types, whose adherence was improved with protrusions, recesses and ribs on their surfaces, were introduced to the market.

In addition, with the widespread use of high-strength concretes, the problem of adherence has gained importance again.

By making use of these explanations, Adherence; We can say that it means “concrete and reinforcement (iron) stick together and work together”.
