Concrete is considered as the most used material in the construction industry. Concrete structures need to be checked and maintained periodically in order to avoid the progression of any cracks to the concrete elements. However, there are some circumstances and problems that causes the deterioration of the concrete structure either totally or partially. In such cases, the repairing techniques, methods and materials cannot serve as a good solution to stop and solve the deterioration. The progression and initiation of damages into the concrete sections may cause a reduction in the durability and strength of the system. Rehabilitation techniques are used to stop the damages and enhance the performance of deteriorated concrete structures where they can restore their strength and durability. These damages may occur due to: the ingress of harmful ions such as chloride and sulfate, freeze and thaw cycles, fire attack, environmental and thermal changes. Several factors and measures can be taken into account while choosing the rehabilitation technique such as the environment surrounding, the section type, the properties of the section and the location of the concrete members that need rehabilitation. Several design equations based on selected standards are reported in order to calculate the properties of rehabilitated structural element. These mainly included the capacity of rehabilitated elements, shear and axial strength.
