Mitigation and Repair Strategies using FRCM to Extend the Service Life of Reinforced and Prestressed Concrete Structures

Abstract

Externally bonded fiber reinforced cementitious matrix (FRCM) for structural members was tested and evaluated as a new class of composite material for repairing and strengthening infrastructure com-ponents. In comparison with fiber reinforced polymer (FRP) composites, FRCM composite has a superior high temperature resistance and improved compatibility with concrete substrates. This experimental work demon-strated the effectiveness of FRCM composite on enhancing the fatigue, flexure, anchorage, and shear capacities of reinforced concrete (RC) structural members. The durability performance of the FRCM composite in terms of resisting different exposure conditions such as freezing and thawing, high temperature and humidity cycles were investigated. The conclusions and summary from this study open the door to use the FRCM composite for repairing and strengthening RC slab decks and/or RC beams for bridges and other structures.
