The use of externally bonded composite materials such as glass fiber reinforced polymers ( GFRP) is a common retrofitting technique that is generally employed. In this paper a new alternative glass and cement-based composite material known as glass textile-reinforced mortar (GTRM), was used for retrofitting. It was mainly found that: (a) GTRM was generally inferior to GFRP in enhancing the flexural capacity of RC beams with an effectiveness ratio between the two systems varying from 0.40 to 1.22, depending on the parameters examined, (b) Doubling the number of GTRM layers (from one to two), the GTRM versus GFRP effectiveness ratio was increased and (c) Providing end-anchorage increased the performance of GTRM-retrofitted beams, but had only limited effect on GFRP retrofitted beams .
