Progress in Textile Reinforced Ductile Cementitious Composite for Structural Retrofitting

Abstract

TRM includes textile fibres made out of inorganic matrix reinforced with continuous knitted or non-knitted fibres. This can be woven at least in two directions to make a fabric mesh; cementitious material is an example for the matrix to impregnate that fabric [1]. Cement-based matrix has an excellent vapor permeability, a good resistance to fire and a good applicability, which means it can successfully be used on wet surfaced at lowTRM is a wide category comprising high strength concrete or mortars and multifilament-Yarns of glass, polymer, or carbon. The cementitious matrix is made from fine aggregate with the maximum size ranging from 1 to 2mm, binder with a volumetric content of approximately 40-50%, and water with water to binder ratio of about 0.3. The high binder content is essential for workability and developing the bond between the fibres and the surrounded matrix.The composite is appropriate for both strengthening existing structures and producing new high-performance constructional elements.TRM composites are characterized by its good tensile performance and high ductility due to the multi-cracks' tolerance.This work is licensed under Creative Commons Attribution 4.0 License JTSFT.MS.ID.000566.
