  45. 45. What is FRP? Composite = combination of two or more materials to form a new and useful material with enhanced properties in comparison to the individual constituents (concrete, wood, etc.) FRPs consist of: 1. Fibres 2. Matrix (Resin, Fillers & Additives)
  46. 46. Uses of FRP in Construction 1. Internal reinforcement of concrete 2. External strengthening of concrete Corrosion of steel reinforcement in concrete structures contributes to infrastructure deterioration Use non-corrosive FRP reinforcement Provide external tension or confining reinforcement (FRP plates, sheets, bars, etc.)
