Evaluation of Flexural Performance of RC Beams Using Polymer Cementitous Mortar

An experimental study to investigate the structural performance of reinforced concrete beams repaired by Polymer Cementitous Mortar in the tension zone is described. Preliminary trials with beams in which beams tensile reinforcing steel was exposed over 100%, 80% and 60% of their length have led to tests on $5\times25$cm beams over a 200cm span to examine the experimental parameter. Attention is concentrated upon overall bending capacity, deflection and crack development of repaired beams.
