“…As a result, the rate of inclusive usage of gypsum by products is quite low. Several methods have been proposed to improve the characteristic of gypsum products, including the inclusion of silicate, slags, clinker, fy ash, and rubber particles [6][7][8][9][10]. Because of their exceptional hardness, durability, and strength, fbers are being used to generate fber-reinforced gypsum composites.…”

“…Considering the current environmental awareness and the increasing interest in advanced lightweight and sustainable materials, the use of natural fbers has become a common practice owing to their appealing characteristics [10][11][12][13][14][15][16]. Te main advantage of using natural fbers is their high energy-absorbing capacity resulting from their low modulus of elasticity [15][16][17][18][19].…”

There has been a great research interest for investigation of new construction materials which can reduce environmental impact and cost, with improved structural performance. Recently, sisal fiber is being used as a reinforcement material in the development of reinforced composites. Here, sisal fiber-gypsum reinforced composites were prepared using the hand lay-up method followed by the compression technique. The effects of weight percentage (Wt. %) of the sisal fiber reinforcement on the mechanical properties of the developed sisal fiber-gypsum composites were investigated experimentally by varying the Wt. % as 5, 10, and 15%. The mechanical properties were tested as per the ASTM standards. The results revealed that the long unidirectional sisal fiber-gypsum composites exhibited higher impact and hardness strengths with lower water absorption behaviour than the short-chopped sisal fiber-gypsum composites. In addition, the impact strength increased with increase in Wt. % for both short-chopped and long unidirectional sisal fiber reinforcement. While the hardness strength decreased with increase in Wt. % for both short-chopped and long unidirectional sisal fiber. The experimental investigation has established sisal fiber as an important reinforcement material for improving the performance of the neat gypsum in a wide range of architectural applications such as ceilings, decorative partitions, and light covers.

“…These challenges result in variations in the mechanical response of fiberreinforced composites, limiting their widespread adoption in practical applications due to durability constraints. 4 Plant-derived fibers have a complex structure with multiple fiber cells containing crystalline cellulose microfibrils interconnected by amorphous substances like lignin, hemicellulose, pectin, waxes, fats, mineral salts, and impurities, which vary depending on plant species, climate, and maturity conditions. 5,6 The fiber cells have a porous wall surrounding a central cavity called the "lumen."…”

This study introduces an innovative method for efficiently integrating abaca fibers into a potassium‐based geopolymer (KGP) material. Geopolymers often suffer from brittleness, and composite designs have been explored as a solution to enhance their strength and ductility. While synthetic reinforcements are commonly employed due to their consistent properties, natural fibers offer a renewable and eco‐friendly alternative. However, their widespread use has been hindered by complex and time‐consuming treatments, resulting in variable morphologies that affect fiber‐matrix adhesion. It is worth noting that previous research has primarily focused on alkali‐activated and cementitious applications, leaving a knowledge gap in understanding its interactions with calcium‐free, metakaolin‐based geopolymers. Consequently, this study aimed to simplify the conversion of raw abaca into uniformly chopped filaments, facilitating their integration into KGPs at levels of up to 7 wt%. The mechanical evaluation revealed exceptional performance, with compressive strengths reaching up to 45 MPa. A thorough analysis confirmed robust, fiber‐matrix adhesion and identified the presence of lignin and cellulose, significantly contributing to the fiber's strength. Flow table tests showcased their versatility, transitioning from high flowability (1 wt%) to complete shape retention (7 wt%). Furthermore, all variations exhibited great ductility, multiple cracking formation, and minimal variability in mechanical properties.

“…The unique attributes of natural fibres, such as their high tensile strength, thermal stability, and inherent fire-retardant qualities, make them exceptionally suitable for integration into FRC applications (Farooqi and Ali, 2019). Beyond their performance benefits, the adoption of natural fibres in FRC fosters a reduction in reliance on non-renewable resources while simultaneously contributing to a reduced environmental impact throughout the entire lifecycle of concrete structures (Ahmad et al, 2022;Boumaaza et al, 2022;Khatib et al, 2022;Shah et al, 2022). As the construction industry increasingly prioritizes sustainability, utilizing natural fibres as a sustainable alternative in FRC signifies a notable stride forward in achieving enhanced spalling resistance while promoting environmentallyfriendly practices.…”

Recent research has shown that the incorporation of fibres, such as steel and polypropylene fibres, in concrete can significantly improve its resistance to spalling under high-temperature conditions. However, the reported outcomes of studies on the spalling performance of Fibre Reinforced Concrete (FRC) vary significantly due to differences in cementitious matrix and fibre types, mix design, and testing techniques. Existing review studies have struggled to systematically and precisely consolidate the diverse aspects of the literature. To address these limitations, this paper adopts the latest approach for mining, processing, and analyzing data to interpret bibliographic data on the fire resistance of FRC. The primary objective of this study is to comprehensively explore the viability of FRC as a fire-resistant and refractory material. In pursuit of this goal, the paper thoroughly reviews various aspects of FRC behavior at elevated temperatures, including pore pressure behaviors. Moreover, this review also discusses spalling behaviors, mechanisms, and residual mechanical properties under high temperatures. The microstructural analysis of FRC is also discussed comprehensively to gain an in-depth understanding of its behavior under elevated temperatures. By analyzing available data, this study aims to shed light on the potential of FRC as a suitable material for resisting spalling in high-temperature scenarios. Additionally, the research delves into prospects and challenges in achieving sustainable FRC with enhanced spalling resistance, considering both material and structural levels.
