matrix, all specimens demonstrated some residual strength prior to the total textile detachment. This is not the case in M1 mortar where the failure is rather sudden. • Fibres presence in M4 mortar demonstrated promising alternatives to M1, M2 and M3 mortars. The mortar shows proper adhesion between matrix and textile. This is because randomly distributed fibres in the mortar matrix alloys textile with matrix, as anchors. • The bond between TRM and substrate became the weak link in this strengthening technique. As a result, all specimens strengthening with M4 mortar failed due to debonding at the matrix-to-substrate. It shows the need for substrate to be prepared before strengthening.
