Abstract
Based on the use of Poly-Urethane-Cement composite material to strengthen the concrete structure element, this study concern of the strain induced in concrete and steel bar of control beam and retrofitted beams with PUC. This is a new technique of externally strengthen the Concrete girder beams, control beam (RC) were constructed same in all cases and tested under four-point bending load. The objectives of this study are to examine the flexural bending strain of retrofitted beam with Poly-Urethane-Cement material (PUC). Experimental results show the PUC have highly deformation and improving the stiffness of beams. The retrofitting beams with PUC have highly deformed comparing with control beam.
