Fabric-reinforced cementitious matrix: A promising strengthening technique for concrete structures

Fabric-reinforced cementitious matrix (FRCM) systems have recently been introduced in the construction industry as a viable alternative strengthening material, to circumvent problems associated with fiber reinforced polymers (FRP). They are made of fabric grids and a cementitious agent which serves as matrix and binder. The cementitious matrix used in FRCM systems has higher thermal capacity and better compatibility with the concrete substrate compared to those of the epoxy resin used in FRP. The use of FRCM composites for strengthening and repair of reinforced concrete structures, though relatively recent, is gradually gaining popularity as an alternative to FRP. This paper presents a critical review of existing research on structural strengthening with FRCM composites, identifies gaps in knowledge, and outlines directions for future research.
