Flexural Strengthening of RC beam using Fabric Reinforced Cementitious Matrix (FRCM)

Authors(2) :-Meera S Prasad, Gopika Moorthy

The advancement of alternative materials and methods for structural rehabilitation is of critical importance to the safety and preservation of the world's habitable heritage. Infrastructure decay caused by premature deterioration of buildings and structures has led to the investigation of several process for repairing or strengthening purposes. One of the challenges in strengthening of concrete structures is selection of a strengthening method that will enhance the strength and serviceability of the structure while addressing limitations such as constructability, building operations and budget. For strengthening RC elements, use of FRP system has become a common technique. But FRP strengthening technique has some limitations and which are related to the epoxy matrix used to embed and bond the fibres. Thus substituting epoxy matrix with cementitious matrix appeared to be the most reasonable solution to improve the overall performance. This new generation of composite system is known as ˜FRCM™ (Fabric Reinforced Cementitious Matrix), which consist of a dry fabric in a cementitious matrix. Due to their superior performance at high temperature, better compatibility with the substrate and improved durability, FRCM systems are a good alternative to FRP system. To present the previous efforts made to develop FRCM as an effective method for strengthening of structures, various journals have been reviewed. This report deals with the study of flexural strengthening of concrete and RC members with the help of various journal reference. It also includes the effectiveness of FRCM with respect to number of confining layer and tensile strength of cementitious matrix. Thus FRCM system are a viable option for flexural and shear strengthening of concrete and RC members.
