• Study of the mechanical behavior of fiber-reinforced concrete through non-destructive testing (2026) · Zastita materijala · doi

  Across this set, durability and long-term performance are evaluated only for glass fiber-reinforced concrete (GFRC) in environmental exposure, and for recycled aggregate concrete with steel fibers; no studies assess long-term durability of natural fiber-reinforced concrete (bamboo, banana, jute, sisal) or hybrid fiber systems under sustained environmental conditions, despite natural fibers' known vulnerability to moisture and degradation.

• A Study on the Influencing Factors of the Mechanical Properties of Steel-Fiber-Reinforced Cement Concrete (2026) · Materials · doi

  Steel fiber-reinforced concrete is studied extensively across multiple grades (M25, M40, M50) and recycled aggregate systems, but natural fiber-reinforced concrete (bamboo, banana, jute, sisal) is evaluated only at lower strength grades or in paver blocks; no study applies natural fibers to high-performance concrete (M50 or above) to assess whether they can achieve the required strength while maintaining cost advantage.

  to that their remain tailored is crucial that hinder The optimal replacement level of Banana Leaf Ash (BLA) in concrete has been shown to vary across different studies, typically ranging from 5% to 25%. This variation suggests further to establish a universally research the diverse accepted mix design requirements of both structural and non-structural concrete elements. While the incorporation of BLA and banana fibers into concrete has demonstrated promising improvements in mechanical properties, durability, and sustainability, several critical research gaps full integration into construction practices. First, the effects of BLA and banana fiber in concrete need the further synergistic interactions between the two materials. Existing studies have mainly focused on individual applications, but a comprehensive understanding of how BLA and banana fiber combine to influence concrete strength, shrinkage characteristics, and toughness is lacking. It is essential to explore how these materials interact at the microstructural level, as their combined effects could lead to significant improvements in both fresh and hardened concrete properties. Additionally, the impact of varying BLA replacement long-term on durability, including resistance to chemical attack, water absorption, and freeze-thaw cycles, requires more detailed study. investigation, particularly regarding concrete levels processes, transportation, The optimization of mix designs considering local environmental conditions, material availability, and performance criteria is needed to ensure the best results for both residential and industrial applications. Furthermore, the economic feasibility of large-scale production and widespread use of BLA and banana fiber in concrete remains unclear. Research should focus on the scalability of these materials, evaluating the cost-effectiveness of their and production incorporation into concrete production. The economic implications of using BLA and banana fiber traditional supplementary cementitious materials, such as fly ash or slag, need to be thoroughly assessed to gauge their potential for large-scale implementation in the construction industry.Although BLA and banana fiber offer significant potential as sustainable comprehensive construction materials, more research is necessary to develop optimized mix designs, understand their synergistic effects, and evaluate and economic viability for both structural and nonstructural concrete applications. in place of performance long-term their 2 ZASTITA MATERIJALA 67 (2026) broj S.

Materials Ordinary Portland Cement (OPC) conforming to standards was used for all concrete mixes. For fine aggregate, river sand of zone-II and 20mm size coarse aggregate was utilized. Banana leaves were collected, dried, and burnt in a controlled environment to produce ash. The ash was then ground to achieve a particle size similar to that of Portland cement. Fibers extracted the pseudo-stem of the banana plant were cleaned, dried, and cut into lengths of 25-50 mm. A commercial superplasticizer (PCE) was used to enhance the workability of the concrete mix. The grade of concrete M30 was designed for concrete mix and its mix proportion is shown in Table 1. from Table. 1.
