The study included testing of six reinforced concrete beams (150 × 100 × 2700 mm): one control beam (without strengthening); one beam strengthened with one layer of textile bonded with epoxy to the tension side of the beam; while the remaining beams were strengthened with one layer, two layers and three layers of textile bonded with mortar. Additional U- shaped strips were used on some of the beams as anchorage to enhance the bond of the textile layers to the concrete surface. The test results indicated that epoxy bonded textile performed better in terms of strength enhancement as the bond was perfect compared to mortar bonded textile where the bond was the main cause of failure. However, the ductility or deformability was slightly better in beams strengthened with mortar bonded textiles. The test results also showed that as the number of layers increases, there is no significant increase in strength due to bond failure. When the U- shaped strips were used along with increasing number of textile fiber layers, the gain in flexure strength and gain in ductility was observed. From the results obtained in this study it is believed that TRMs is a potential solution for the structural upgrading of concrete structures provided the bond between the textile layer and the concrete surface is maintained.
