Flexural capacity of a Textile Reinforced Mortar(TRM) was investigated by an experimental study. The test program was accomplished on reinforced concrete(RC) slabs consisted of concrete(average compressive strength of 22.23 MPa) and rebar(strength class of SD400). RC slab had 450 mm and 150 mm in size and 2,600 mm in clear span. Strengthening was accomplished by applying carbon-fiber mesh in layers of mortar. Control slab(unstrengthened) and six slabs strengthened with TRM were fabricated to confirm the reinforcing performance in this study. Test variables considered amount of reinforcement and use of anchorage. As a results, it was validated that the flexural capacity of slabs strengthened with TRM increased from 159.9% to 285.2% according to the amount of TRM compared with unstrengthened slab. Experimental results indicated that there are increase in ductility as well as load carrying and deformation capacities when using multiple layers of textile.
