Using fibre reinforced cement composites for RC structures upgrading

Repair and strengthening existing structures are widely recognized as sustainable solutions to preserve the built environment from aging and natural hazards. Current research is exploring the adoption of inorganic composite materials, such as Fiber Reinforced Cement Composites (FRCC), for repairing existing RC buildings and infrastructure as a replacement of the original concrete cover, due to its good durability properties and resistance to high temperature. The present study explores the effectiveness of adopting such FRCC light jacketing also for the upgrading of existing RC columns. Results of experimental campaigns conducted over the past years at University of Naples Federico II (Italy) are critically discussed to highlight strengths and limitations of such technique.
