Abstract
This paper presents the details of flexural behaviour of damaged RC beams strengthened with Ultra High Performance Concrete (UHPC) overlay. Details of UHPC including mechanical properties are described in detail. Control RC beams of size 100 × 200 × 1,500 mm with M30 grade of concrete are tested up to failure. Damage is introduced by preloading the RC beams up to 80 and 90 % of the failure load of control RC beam. UHPC overlay is added on the tension face of the beam with epoxy and tests are conducted for flexural behaviour. It is observed that there is significant increase in load carrying capacity and ductility in the case of preloaded RC beams strengthened with UHPC overlay.
