“…World fiber production, including in steel, glass, and polymers, has been steadily increasing in the past few decades and has garnered increasing interest with the use of sustainable fibers produced from renewable, biodegradable, waste, recycled, available, and low-cost resources becoming a focal point. In this sense, vegetable and cellulosic fibers have already been used as reinforcement in cementitious materials for low-to medium-performance structural applications [5,[10][11][12][13]. Textile waste fiber could be another sustainable alternative for reinforcement in cementitious composites.…”

Currently, millions of tons of textile waste from the garment and textile industries are generated worldwide each year. As a promising option in terms of sustainability, textile waste fibers could be used as internal reinforcement of cement-based composites by enhancing ductility and decreasing crack propagation. To this end, two extensive experimental programs were carried out, involving the use of either fractions of short random fibers at 6–10% by weight or nonwoven fabrics in 3–7 laminate layers in the textile waste-reinforcement of cement, and the mechanical and durability properties of the resulting composites were characterized. Flexural resistance in pre- and post-crack, toughness, and stiffness of the resulting composites were assessed in addition to unrestrained drying shrinkage testing. The results obtained from those programs were analyzed and compared to identify the optimal composite and potential applications. Based on the results of experimental analysis, the feasibility of using this textile waste composite as a potential construction material in nonstructural concrete structures such as facade cladding, raised floors, and pavements was confirmed. The optimal composite was proven to be the one reinforced with six layers of nonwoven fabric, with a flexural strength of 15.5 MPa and a toughness of 9.7 kJ/m2.

“…Studies at the structural scale [13][14][15] or the composite scale [16][17][18][19] can also be found. However, comprehensive experimental/analytical studies from materials to structural scale are still missing [20,21]. Structural scale tests (diagonal tension or out-of-plane tests on TRM-strengthened masonry) are still few and mainly focused on the effect of textile and substrate types [22,23], the number of textile layers [24], and symmetrical or asymmetrical application of the repair [13,25,26].…”

A multi-level investigation on the mechanical response of TRM-strengthened masonry

This paper presents a multi-level experimental and analytical investigation on the mechanical performance of TRM composites used for strengthening existing masonry structures. Micro (fabric-tomortar bond), meso (TRM-to-substrate bond), and macro (TRM tensile response and in-plane and the out-of-plane ressponse of TRM-strengthened masonry) response of TRMs are combined and investigated in-depth for this reason. These results help to understand the mechanisms controlling the response of these composites and their performance at the structural scale.

“…Different varieties of plant fibers have been used for the same purpose in the last years: Raw hemp fiber (Formisano et al, 2017), hemp fiber mesh (Menna et al, 2015), flax fibers and fabrics (Ferrara et al, 2020), jute (Formisano et al, 2019), palm oil fiber (Raut and Gomez, 2016), date palm fiber (Benmansour et al, 2014), banana leaves, reed, palm tree leaves and coconut seeds (Al-Zubaidi, 2018).…”

Old masonry buildings represent the largest part of traditional constructions. Generally, they are both seismically vulnerable and thermally dispersive. Therefore, the need for seismic and thermal retrofitting aimed at reducing their vulnerability and environmental impact has motivated research efforts towards sustainable retrofitting solutions. This study presents a literature review of the approaches currently available for masonry retrofitting. Specifically, it highlights the use of fiber in textile form i.e., Textile Reinforcement Mortar (TRM), as Fiber Reinforced Polymer (FRP) and natural fibers (animal and plant sources) to masonry retrofitting. In addition, specific attention is devoted to the integrated (structural and thermal) fiber-based integrated retrofitting techniques that are becoming very important in the last years.
