ABSTRACT
Reinforced concrete is far from homogeneous. It is built up of steel and concrete and the concrete itself is not homogeneous neither. Reinforced concrete elements are basically designed so that the concrete can carry the compressive stresses and the steel can resist the tensile stresses. Therefore a good force transfer between the two materials is necessary which can only be achieved by an interaction between both materials, which is provided by bond between the reinforcement bars and the concrete.
