Fire Performance of Fibre-Reinforced Polymer Systems Used for the Repair of Concrete Buildings

This Update reviews NRC-IRC research on the fire resistance of externally bonded, fibre-reinforced polymer (FRPs) systems used for repairing concrete building members. The research showed that FRP systems that include specially designed insulation can enable repaired or strengthened concrete members to exceed the 4-hour fire resistance requirements of building codes.

Repairs to Restore Serviceability in Concrete Structures

Lasting repairs of deteriorated concrete structures depend on careful selection of materials and methods suitable for the service and application conditions. This Update describes the factors that facility managers and designers need to consider to ensure durable repairs. The factors discussed address the restoration of serviceability and the correction of cosmetic defects and are not applicable to failures resulting from overloading. Full story
