Abstract : The subject of this paper is the experimental analysis of possibilities to increase the ultimate flexural load carrying capacity by strengthening steel reinforced concrete structures using textile reinforcement. The textile reinforcement consists of open textile structure made of continuous kevlar rovings. The adhesive used for bonding the fabric to the beam is organic resin (Epoxy) and inorganic binder (Cement based mortar). The testing on rectangular beams was aimed at investigating the parameters like inorganic mortar versus organic resin for the textile reinforcement, number of textile layers (one, two and three) and pattern of wrapping (bottom, Uwrapping and full). In order to find the flexural behaviour, the beam is subjected to two point loading test. A total of nineteen beams were cast, one among them is control beam and the binder for the first nine beams was epoxy resin and for the remaining ones was cement based mortar. The load deflection behaviour and load carrying capacity of the beams were observed during the experiment and discussed. A comparative study is made out from the outcome of the experiments between epoxy bonded beam and cement mortar beam. The optimum number of layers and feasible wrapping system with respect to the load carrying capacity were also reported.
