Abstract

This study deals with the experimental investigation for enhancing the flexural capacity of RC beams using epoxy resins (adhesive). Retrofitting method used is concrete jacketing. Three concrete beam specimens with dimensions of 150 mm height, 1800 mm length and 100 mm width were casted in the laboratory. As per the design of the beam, 10j and 8j bars are being provided in tension and compression zones respectively. All beams were geometrically sound (kept constant). Beams were weak in flexure and were strengthened utilizing concrete jacketing method. All the beams were simply supported at both ends with 1675 mm effective span, 125 mm bearings, loaded under more real loading conditions, i.e. center loading and tested till failure by the effect of gradually increasing super imposed load. The deflection of beams is measured. Load deflection curve of control RC1, RC2 and RC3 beam when compared to load deflection curve of retrofitted RC1, RC2 and RC3 beam shows that the retrofitted RC beam shows satisfactory results as compared to the control beam i.e. control beam fails on a maximum load of 30.66 KN while retrofitted RC beam fails on a maximum load of 23 KN. Load deflection characteristics of RC beam and Retrofitted RC beam show retrofitted beams attain about 75% strength of control beam.
