Application of Natural FRCM Composites in Structural Strengthening/Rehabilitation: State-of-the-Art Analysis
Résumé
In recent decades, the vulnerability of structures in the building sector has led to the need to improve the structural performance of existing and new structures. Composite materials referred to as textile-reinforced mortars (TRM) and known in the literature as textile-reinforced concrete (TRC) or fabric-reinforced cementitious matrix (FRCM), have been extensively investigated as a promising alternative to fibre-reinforced polymers (FRP) for strengthening concrete or masonry elements.
These cementitious matrix composites offer substrate compatibility, lower cost, and better performance at high temperatures compared to FRP. In addition, the use of natural fibres in FRCM has increased significantly due to their good mechanical properties and lower the environmental impact of construction materials.
This paper presents a brief overview of the work on strengthening structural elements with natural FRCM. It gives an overview of the different parameters affecting the effectiveness of natural FRCM, the different strengthening techniques and some applications to improve mechanical performance.
