“…Besides, the composite strengthened layer combined with FRP textile and ECC can provide effective lateral confining stress to the retrofitted RC columns and delay the yielding of the longitudinal bar. AL-Gemeel and Zhuge [70] investigated the strengthening effect of basalt fiber textile combined with ECC to confine RC columns. The effect of ordinary FRP strengthening decreased owing to the square shape of the column and brittleness of FRP, so that ductile ECC was incorporated and a circular mold was adopted to overcome these drawbacks.…”

“…Two different strengthening schemes were used: (1) Twosided retrofitting system, i.e., applying ECC and CFRP to the front and rear faces of the joints; and Figure 12. Retrofitting details of RC square columns changed to a circular shape (adapted from [70]). Researchers also proposed several formulae to predict the shear capacity of the strengthened RC columns [68]:…”

This paper presents a review of the recent work assessing the performance of building structures strengthened with engineered cementitious composite (ECC). ECC characterizes tensile strain hardening and multiple cracking properties, as well as strong interfacial bonding performance with substrate concrete, which makes it a promising retrofitting material. A lot of researches have been conducted on reinforced concrete (RC) structures, including beams, columns, beam–column joints, and fire-damaged slabs, strengthened with ECC material, and an extensive collection of valuable conclusions were obtained. These strengthening systems usually combine ECC with FRP textiles or steel bars to form a composite strengthening layer. The review demonstrates that ECC strengthening can greatly improve the performance of RC structures.

“…In very recent research, Al-Gemeel and Zhuge have produced a new generation of TRM where they used engineered cementitious composite (ECC) to bond basalt textile fibres [17,18]. It was found that ECC could be a very successful cement-based matrix to impregnate textile fibres due to the strain-hardening performance and the high workability.…”

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.

“…The ultimate tensile strain of ECC can reach larger than 3%, approximately 200–600 times that of normal concrete, yet the fiber volume fraction is typically less than 2% (Li and Leung, 1992). Since its invention in the early 1990s, ECC has attracted extensive research and has been more and more widely used in practice (AL-Gemeel and Zhuge, 2018; Kim et al, 2004; Li et al, 2019; Li and Leung, 1992).…”

Extensive research has been conducted on the uniaxial tensile and compressive behavior of engineered cementitious composites. Despite the high tensile ductility and high toughness of engineered cementitious composites, transverse steel reinforcement is still necessary for high-performance structural members made of engineered cementitious composites. However, very limited research has been concerned with the compressive behavior of steel-confined engineered cementitious composites. This article presents the results of axial compression tests on a series of circular engineered cementitious composite columns confined with steel spirals. The test variables included the engineered cementitious composite compressive strength, the spiral pitch, and the spiral yield stress. The test results show that steel-confined engineered cementitious composites in the test columns exhibited a very ductile behavior; the steel spiral confinement contributed effectively to the enhancement of both strength and ductility of engineered cementitious composites. The test results were then interpreted by comparing them with the predictions from some existing models. It was found that the existing models previously developed for confined concrete failed to predict the compressive strength of steel-confined engineered cementitious composites with sufficient accuracy. New fitting equations for the compressive properties of steel-confined engineered cementitious composites were then obtained on the basis of the test results of this study as well as those from an existing study.
