“…Natural fibers, such as fibers of mineral origin like basalt [ 12 , 212 , 225 , 226 ], and fibers of plant origin, like sisal [ 72 , 227 ], as well as banana [ 228 , 229 ], can also be used as reinforcement of HPC and UHPC. Their main advantages are the fact that they are renewable and eco-friendly resources.…”

This review article proposes the identification and basic concepts of materials that might be used for the production of high-performance concrete (HPC) and ultra-high-performance concrete (UHPC). Although other reviews have addressed this topic, the present work differs by presenting relevant aspects on possible materials applied in the production of HPC and UHPC. The main innovation of this review article is to identify the perspectives for new materials that can be considered in the production of novel special concretes. After consulting different bibliographic databases, some information related to ordinary Portland cement (OPC), mineral additions, aggregates, and chemical additives used for the production of HPC and UHPC were highlighted. Relevant information on the application of synthetic and natural fibers is also highlighted in association with a cement matrix of HPC and UHPC, forming composites with properties superior to conventional concrete used in civil construction. The article also presents some relevant characteristics for the application of HPC and UHPC produced with alkali-activated cement, an alternative binder to OPC produced through the reaction between two essential components: precursors and activators. Some information about the main types of precursors, subdivided into materials rich in aluminosilicates and rich in calcium, were also highlighted. Finally, suggestions for future work related to the application of HPC and UHPC are highlighted, guiding future research on this topic.

“…Figure 1 shows the shape of the fibers after extracting it from the stem of the banana plant. The fibers were extracted with a length of 1.5 m, and these fibers were converted into bars by manual process in the lab in an attempt to use it as an alternative to traditional steel bars [12]. The finite element analysis is widely applied in engineering purposes through different software programs, giving a huge probability for solving issues of structural analysis.…”

One of the challenges of the century is to reach compatibility between the required resistance and the usage of lightweight building materials that may negatively affect the mechanical properties. Natural fibers nowadays are used as enhancers in the industrial field. Hence, the fibers contribute by giving an ideal solution to improve mechanical proprieties of the structural elements such as tensile and impact strength. In previous studies, the use of natural fibers as reinforcement in construction materials has increased. Natural fibers have a lot of characteristics such as being strong, lightweight, inexpensive, and eco-friendly. This paper aims to investigate the performance of banana fiber bars (BFB) as reinforced material. Through this study, the development and characterization of natural fibers-based composite beams were observed. After the beams were designed, several types of finite element analysis were conducted using ‘ANSYS’ nonlinear finite element program under one-point loading. Results show good correlations between experimental and predicted results.

“…Recently, natural fibres have been advanced as an alternative reinforcing material to conventional synthetic fibres owing to their environmental and economic benefits [13][14][15][16][17][18][19][20]. Natural fibres are readily available, biodegradable, cheaper, and recyclable, and they have been observed to have high tensile and flexural strengths as well as low elongation at break, hence rendering them widely accepted in construction industry [21][22][23][24].…”

“…Natural fibres are readily available, biodegradable, cheaper, and recyclable, and they have been observed to have high tensile and flexural strengths as well as low elongation at break, hence rendering them widely accepted in construction industry [21][22][23][24]. Elbhiery et al [20] compared and summarised the mechanical properties of various plant fibres and E-glass. However, studies conducted on the performance of natural fibres have pointed to durability-related problems, such as their inability to deal with external damage due to moisture absorption, biological microorganisms, sulphate, or chloride attack, as well as internal damage mainly because of compatibility issues between fibres (due to presence of organic substances such as waxes, lignin, and pectin) and alkaline-cement paste environment [13,15,[25][26][27][28][29].…”

This experimental study aimed at investigating the impact of addition of banana fibres on the mechanical (compression, splitting tension, and flexure) and microstructural (microscopic morphology and Energy Dispersive X-ray Spectroscopy) properties of concrete. Concrete mixes comprising of banana fibres of varying fibre lengths (40, 50, and 60 mm) and fibre contents (0.1, 0.2, 1.0, 1.5, and 2.5%) were assessed. Addition of banana fibres to concrete was observed to significantly impact on compressive strength only at lower fibre contents of up to 0.25% for all fibre lengths. Fibre length had no significant impact on compressive strength at lower fibre contents of up to 0.25%, but shorter fibres were observed to perform better than longer ones at higher dosages more than 0.25%. Increase in fibre content positively impacted on tensile strength of concrete at relatively lower fibre dosages of up to 1%. Similarly, fibre length impacted on tensile strength of concrete at lower fibre contents of up to 1% and, longer fibres were observed to be more effective than shorter ones. Addition of banana fibres generally did not greatly contribute to flexural strength of concrete but had a marginal impact only when shorter fibres were used at lower fibre dosages. Also, microstructure of concrete was improved through better bonding between the fibres and the matrix and reduction in porosity of the matrix, which resulted in improved mechanical properties of the composite. Banana fibres further contributed to changes in phases of the composite structure of Banana fibre-reinforced concrete (BFRC) through a reduction in its interplanar spacing and lattice structure. For optimal purposes, addition of banana fibres should be limited to a maximum of 1% fibre content preferably using shorter fibre lengths. Further research to improve flexural strength of BFRC to meet minimum technical requirements is required before it can be considered for structural applications.
