“…These specimens were made using crushed CS waste as CA to produce lightweight concrete. Shah et al [43] examined the mechanical characteristics of concrete incorporating recycled aggregates and coconut fibers. Their primary focus was on advancing the development of sustainable and ductile cementitious composites by repurposing coconut and construction waste materials.…”

Due to urbanization, demand for concrete has been increasing up to 10 million cubic meter per year. Therefore, there is an urgent need to reduce the requirement for ingredients such as cement, sand, and aggregate. Cement serves as a binding material in concrete, which is being used in the construction industry since ancient times [1,2]. The admixtures are added in order to reduce the demand and supply gaps for cement, and the most common admixture is coal ash (CA) obtained from thermal power stations.

“…The collected data were adapted based on the cradle-to-gate scenario. The EI of JF was taken as similar to that of the recycled coconut fibre, since, in this research, JF was considered as a recycled material [47]. The study considered the environmental impact of transporting the concrete mixtures by lorry, which was calculated to be 6.57 × 10 −5 kg-CO 2 per kilogram per kilometre.…”

The brittleness of plain concrete (PC) is a result of its lack of tensile strength and poor resistance to cracking, which in turn limits its potential uses. The addition of dispersed fibres into the binding material has been demonstrated to have a positive impact on the tensile properties of PC. Nevertheless, using new or engineered fibres in concrete significantly increases the overall cost and carbon footprint of concrete. Consequently, the main obstacle in creating environmentally friendly fibre-reinforced concrete is the traditional design process with energy-intensive materials. This study investigated how the engineering properties and life cycle impact of concrete were influenced by varying the volume fractions of jute fibre (JF). The impact of incorporating silica fume (SF) as a partial replacement of Portland cement was also studied. The studied parameters included mechanical behaviour, non-destructive durability indicators, and the life cycle impact of concrete using JF and SF. The efficiency of JF in mechanical performance improved with the increase in age and with the addition of SF. When using both SF and 0.3% JF, there was an improvement of around 28% in the compressive strength (CS). When 0.3% JF was added, in the presence and absence of SF, the splitting tensile strength (STS) improvement was around 20% and 40%, respectively. The addition of JF improved the residual flexural strength (FS) and flexural ductility of PC. The SF addition overcame the drawbacks of the poor resistance of JF-reinforced concrete (JFRC) against water absorption (WA) and rapid chloride ion penetration (RCIP).

“…Better performance in low cost can only be achieved by using waste fibrous material in our surrounding like waste coconut fiber, glass fiber, steel fiber, polypropylene fiber etc. The use of waste materials in concrete will reduce the economic factor in major construction projects (Ahmad et al, 2022;Aslam et al, 2022;Das et al, 2020;Shah et al, 2022).…”

Mostly used material is concrete which has versatile quality for construction works. Fibrous concrete have significant factor that improve the scale and value to concrete for humid environments with significant role. Day by day abundant demand and use of concrete is increasing. It is considered as a 2nd largest building material due to the major productivity. By the use of fibrous concrete, some bonding and environmental issues have been addressed. Keeping in this view, an experimental based study is conducted to evaluate the strength of fiber reinforced concrete at different percentages 0%, 0.5%, 1.0%, 1.5% and 2.0%. All percentages are added by the weight of concrete with all fibers. In this connection, one hundred and fifty-three cylinders of five mixes are prepared. Workability checked of fresh concrete during the pouring of concrete cylinders. Poured cylinders’ samples are left for different curing ages at 7 and 28 days. One hundred and two cylinders for compression at 7 and 28days but fifty-one cylinders for split tensile test at 28days with all fibers i.e. glass fiber, steel fiber, coconut fiber and polypropylene fiber. After curing, compression and split tensile tests are performed to check the strength of hardened concrete. Workability of five mixes lies between 40-90mm.Fibrous concrete is suitable for humid environment where high strength and voids less concrete are required. Addition of fibers in concrete may improves the strength parameters as well as to increase the bonding and tensile properties of concrete. It reduces the quantity of water to be used in concrete. Also the use of different types of fibers has been proved to be economical and is considered as environmental friendly construction material.
