“…Fiber is frequently portrayed by a helpful parameter; the angle proportion which is the proportion of its length to the distance across. The use of fibers in concretes has well known advantages, as it helps in controlling the cracking, it reduces the porousness of concrete, it produces more impact resistance, and it also increases strength, ductility, shatter, abrasion resistance and delays cracking [52][53][54][55][56][57][58][59][60]. On the other hand, human hair presents properties such as unique chemical composition, high tensile strength, and high elasticity, which make it a useful material to be contained in concrete.…”

The sustainable use of agricultural, industrial and human waste products as raw materials in the construction industry has been extensively investigated. This study aimed to conceive an innovative concrete composition mainly using recycled materials, which, as a result as waste from human activities and natural organic growth, such as animal bones and human hair, will be used in different mixtures in order to prepare concrete specimens. More specifically, the effect of these materials upon the final concrete strength was investigated, as well as how their petrographic characteristics may influence the durability of concrete specimens. Special emphasis was placed on the effect of the artificial increase in bone and hair microroughness and how these can improve the mechanical strength of the final product. The research results point towards the fact that the percentage of the replacement of natural aggregate rocks by animal bones tends to be enhanced by the increase in their microroughness using quartz primer. In addition, the use of bones with increased artificial microroughness and a certain percentage of human hair with increased microtopography seems to be the ideal mixture for the replacement of natural aggregates for the production of normal concrete.

“…Response surface methodology (RSM) was used to find the best suitable concentration of hair fiber for concrete reinforcement. It was observed that with 3.2% hair by volume of concrete and a hair strand length of 0.752 inches, an optimal concrete strength of 38.15 MPa can be achieved [13]. It was found that bending stress of 5.68 MPa was produced at 2% of hair fiber addition [14], [15].…”

For a long period, materials like steel, jute, wood, etc. are been taken into practice for concrete fabrication. The reinforcement of concrete structures provides good stability and improves the mechanical properties of the material. The overgrowing population results in demand for infrastructures, which in proportion increases the production of concrete. To reduce the after effect of concrete production and prevent the use of raw materials, the utilization of waste elements as a substitution for concrete constituents is exercised by researchers to decrease the chance of degradation by construction pollution and landfilling of waste. The use of waste Human Hair Fiber (HHF) as concrete fabrication is a step forward toward sustainable construction. The current study has been performed to examine the effect of HHF reinforcement on concrete by determining the strength features of the concrete with human hair of lengths 20, 50, and 80 mm at 1%, 1.5%, and 2% addition of HHF by the weight of cement on. However, it was found that a 1.5% addition of human hair of lengths 50 mm and 80 mm shows the maximum compressive and flexural quality whereas, a 1% addition of human hair with 50 mm length as given the maximum 28 days tensile strength.

“…Petrounias P. et al [17] studied the preparation of concrete and evaluated its mechanical properties using hair fibers as ditives. Furthermore, studies [18][19][20] have demonstrated the positive effects of incorporating various fiber materials such as polypropylene and glass into road subgrade mixtures in different proportions. These studies conducted comparative analyses between mixtures with fibers and those without fibers, assessing mechanical and physical properties such as uniaxial compressive strength and flowability.…”

Numerous studies have been conducted on fiber-reinforced concrete; however, comparative investigations specifically focusing on the utilization of fibers in CLSM remain limited. In this study, we conducted a systematic investigation into the mechanical properties of controlled low-strength material (CLSM) by manipulating the length and doping amount of fibers as control variables. The 7-day compressive strength (7d-UCS), 28-day compressive strength (28d-UCS), and 28-day splitting strength of CLSM were employed as indicators to evaluate the material’s performance. Based on our comprehensive analysis, the following conclusions were drawn: (1) A positive correlation was observed between fiber length and material strength within the range of 0–6 mm, while conversely, a negative correlation was evident. Similarly, when the fiber doping was within the range of 0–0.3%, a positive correlation was identified between material strength and fiber doping. However, the strength of CLSM decreased when fiber doping exceeded 0.3%. (2) SEM and PCAS analyses provided further confirmation that the incorporation of fibers effectively reduced the porosity of the material by filling internal pores and interacting with hydration products, thereby forming a mesh structure. Overall, this study offers valuable insights into the manipulation of fiber length and doping amount to optimize the mechanical properties of CLSM. The findings have important implications for the practical application of CLSM, particularly in terms of enhancing its strength through fiber incorporation.
