Natural fibers derived from plant wastes possess a negligible carbon footprint and a high tensile strength. Therefore, researchers are focusing on the technical evaluation of cementitious materials with bio-based fibers. The stems of the banana plant consist of high-quality textile-grade fiber bundles possessing high tensile strength and toughness. Owing to these characteristics banana stem fiber (BSF) can be used as a reinforcement for plain concrete. Therefore, this study is devoted to the evaluation of the properties of concrete with various concentrations of BSF. The performance of BSF in concrete was also compared with artificial polypropylene fiber (PPF) at the same volumes of fibers (i.e., 0.25, 0.5, and 1%). The results revealed that 0.25% and 0.5% volumes of BSF were highly useful to the tensile and flexural strength of concrete. However, residual compressive and tensile strength improved with the increasing volume of BSF. At 0.5% BSF, compressive strength, splitting tensile strength, and flexural strength of concrete experienced net improvements of 6%, 40%, and 10%, respectively. The mechanical performance of BSF was comparable to that of the artificial PPF. Electrical resistivity increased with the rising fiber volume. Whereas, ultrasonic pulse velocity gradually decreased with rising fiber content and reduced by 7% at 1% BSF. Scanning electron microscopic (SEM) analysis revealed a negligible shrinkage of BSF filaments in the cementitious matrix. This behavior was contrary to that observed with other natural fibers. • Waste stems of banana plants were processed into fiber reinforcement for concrete. • Performance banana fibers in concrete were compared with polypropylene fibers. • Life cycle analysis was conducted to evaluate emissions of concrete mixes. • Non-destructive properties of studied mixes were evaluated. • Banana fiber reinforced concrete is eco-friendlier than conventional concrete.

Effect of utilising ferrosilicon and recycled steel fibres on ultra-high-strength concrete containing recycled granite

Accumulating vast amounts of pollutants drives modern civilization toward sustainable development. Construction waste is one of the prominent issues impeding progress toward net-zero. Pollutants must be utilized in constructing civil engineering structures for a green ecosystem. On the other hand, large-scale production of industrial steel fibers (ISFs) causes significant damage to the goal of a sustainable environment. Recycled steel fibers (RSFs) from waste tires have been suggested to replace ISFs. This research critically examines RSF’s application in the mechanical properties’ improvement of concrete and mortar. A statistical analysis of dimensional parameters of RSFs, their properties, and their use in manufacturing various cement-based composites are given. Furthermore, comparative assessments are carried out among the improvements in compressive, split tensile, and flexural strengths of plain and RSF-incorporated concrete and mortar. In addition, the optimum contents of RSF for each strength property are also discussed. The influence of RSFs parameters on various strength properties of concrete and mortars is discussed. The possible applications of RSF for various civil engineering structures are reviewed. The limitations and errors noticed in previous review papers are also outlined. It is found that the maximum enhancement in compressive strength (CS), split tensile strength (STS), and flexure strength (FS) are 78%, 149%, and 157%, respectively, with the addition of RSF into concrete. RSF increased cement mortars’ CS, STS, and FS by 46%, 50.6%, and 69%, respectively. The current study encourages the building sector to use RSFs for sustainable concrete.
