Abstract

Reinforced concrete jacketing is one of the widely used repairing techniques for beams and
columns. The aim of this research is to evaluate the efficiency of using concrete jackets using
different reinforcements and thicknesses. The behavior of repaired reinforced concrete defected
beams is investigated under flexural effect. The tested beams are preloaded up to 70 and 90% of
their ultimate capacity then, repaired using concrete jackets. The main variables are thickness of
concrete jacket (3, 5 cm), diameter of reinforcing steel bars (8, 10 mm) and concrete jacket type.
The experimental results showed that, repairing using concrete jackets enhances the load capacity
up to 378%. Increasing jacket thickness enhances the structural performance of the tested beams
and in the same time increases its weight. It also increases the stiffness compared to the control
beam and consequently the repaired concrete beams indicated a brittle manner compared to the
ductile failure of the control beams.
