“…Many attempts have been made to use natural fiber polymer composites to fabricate wall panels, roof sheets, temporary shelters, and post office boxes, but such composites fail in wet conditions, either by swelled fibers or by delamination, due to crack growth between plies. 39 Burgueno et al have shown that bio-composites are able to be used as load-bearing members by arranging their cellular materials in a way that increases their structural efficiency. To prepare laboratory-scale periodic cellular beams and plates, they impregnated hemp and flax fibers with unsaturated polyester resin.…”

Natural fiber-reinforced composites (NFRCs) are expected to find growing applications in near future, especially in Europe where stringent environmental codes are being legislated and public pressure for their enforcement is increasing. Study has shown that NFRCs are also gaining recognition among civil engineers as a viable alternative to traditional materials for use as concrete reinforcement in load-bearing structural members as in building frames and bridge decks. The present review strives to provide a brief overview of NFRCs, state-of-the-art developments in their manufacture, and examples of their structural applications. Another aspect of the review involves investigation of the challenges facing the use of fiber composite materials in civil engineering. These include the high manufacturing costs, difficulties associated with appraisal of its potential benefits, uncertainties about their properties, lack of understanding among civil engineers of the material and its service life, and the relatively small battery of standards developed for the composite industry. Finally, the study will conclude with the prospects of bio-composite applications and the emerging trends in novel bio-composites for future structural applications.

“…Generally, Concrete and mortar are brittle materials with low tensile strength and low deformation capacity [39]. The incorporation of the fibers in cementitious matrix mainly improves tensile, flexural, impact strength and flexural toughness [40][41][42]. Industrial and natural fibers have been studied by many researchers [43][44][45].…”

The behavior of non-reinforced green mortar with fibers has been observed. Different green mortar mixes have been prepared using different percentages of waste glass powder (WGP), steel slag (SG) and silica fume (SF).The properties of flow, density, ultrasonic pulse velocity (UPV), compressive and flexural strengths have been tested for such green mortar in the first phase of the experimental work. The selected green mortar mix that gives good properties with the acceptable ranges of cement replacement by such cementitious materials has been utilized to achieve the second phase of the experimental work. Thus, the uses of human hair fibers, sisal fibers and stainless steel nails fibers in the form of individual and hybrid fibers system and testing for the same properties mentioned above have been performed. The third phase includes the cost estimation for the said mortar. Whereas, the last phase deals with analysis of the results using the integrated AHP and TOPSIS method for selection the best performance of the green mortar. The results of mono sisal fiber, human hair fiber and stainless nails fiber by 0.75, 0.75 and 2% of volume fraction respectively, exhibited the highest increase in compressive strength, flexural strength, UPV and density compared with other percentages.

“…The natural fibers show several advantages over synthetic fibers and reinforcing steel, for example, abundance, biodegradability, recyclable, easy to use, nontoxicity, low density, no abrasiveness, good thermal properties, good toughness properties and good values of elasticity modulus. However, they exhibit high absorption capacity of water and a poor compatibility with the matrix, which leads unpredictable consequences on the concrete properties (Abiola, 2017;Kılınç, Durmuşkahya, & Seydibeyoğlu, 2017).…”

“…• Alkalinity decrease of the concrete, by replacing partially the portland cement by pozzolans (Wei & Meyer, 2015), or by combining cement with siliceous materials and clay minerals (Wei & Meyer, 2016, 2017). • Fibers modification through different techniques, such as polymerization with methane's cold plasma (Li, Zhou, & Guo, 2017;Ridzuan, Majid, Afendi, Azduwin, & Aqmariah, 2015), hornification (Claramunt, Ardanuy, García-Hortal, & Filho, 2011), or hydrothermal treatment (Sawsen et al, 2015).…”
