Carbon Fibre Reinforced Polymer (CFRP) composites have been progressively more utilized to strengthen the concrete members to improve its flexural performance. Flexural capacity of CFRP strengthened concrete members mainly hinge on controlling probable failure modes. The inter-facial bond failure takes place owing poor surface preparation for FRP application which grounds a bond failure between concrete and adhesive eventually. Preparation of concrete substrate plays a significant role in terms of engendering strong bond between FRP - concrete interface. Achieving uniform surface roughness...
