“…It is feasible to add bers to the concrete mix in order to prevent brittle failure and increase mechanical qualities. HPPM stripes are cementitious composite material having bers scattered throughout, such as steel, polymer, polypropylene, carbon, glass, and others (Blazy and R. Blazy 2021). The steel bars protection from corrosion and sulfate attack, as well as water and ions in ltration through pores as well as cracks, is linked to improving the longevity of reinforced concrete (Kumar Mehta and Burrows, 2001).…”

“…Plastic shrinkage at an early age is commonly acknowledged as one of the principal causes of concrete cracks. As a result, both the insertion of bers and the replacement of traditional reinforcement with bers appear to be quite favorable in terms of longterm development (Blazy and R. Blazy 2021). Polypropylene ber reinforced concrete was investigated by Islam and Gupta (2016) in an experiment.…”

This research presents a new method for determining the impact of healthy personal protection materials HPPM stripes, such as surgical masks, protective suits, overhead and safety foot shoes, on the durability, physicomechanical characteristics of concrete for use in architectural forms. As a result of the current global epidemic caused by Coronavirus, the use of (HPPM) such as surgical masks, protective suits, overhead and safety foot shoes has increased considerably (COVID-19). COVID-19's second and third waves are currently affecting various countries, necessitating the use of face masks (FM). As a result, millions of single FS have been discharged into the wild, washing up on beaches, floating beneath the seas, and winding up in hazardous locations. The effect of stripes fibers on physicomechanical aspects of concrete, such as workability, UCS, FS, IMs, spalling, and AbR; sorptivity, Sw; n; water penetration, permeability, and economic and eco-friendly aspects, was also discussed. With a focus on HPPM especially single-use face masks, this research investigates an innovative way for incorporating pandemic waste into concrete structures. SEM and XRD were also employed to analyze microstructures and the interfacial transition zone, as well as to identify the elements. HPPM was found to have a pore-blocking effect, which reduced permeability and capillary porosity. It was also discovered that the best concentrations of HPPM, particularly masks, were applied by volume at 0 %, 0.1, 1.5, 2.0, and 2.5 %. The usage of single-use face masks increased the strength qualities and overall performance of the concrete samples. The tendency of growing strength began to disappear around 2%. The results of this investigation show that stripe content has no effect on compressive strength. The stripe, on the other hand, is critical in determining the flexural strength of concrete. A SEM was used to analyze the microstructure of concrete. HPPM fibers are discovered to act as bridges across cracks, enhancing the matrixes transfer capability. From a technological and environmental standpoint, the study found that using healthy personal protection materials fiber in the production of concrete is viable.

“…Normally, the conventional concrete using OPC has high compressive strength but low tension performance. Hence, the fibers were added to the concrete mixture to improve the tensile strength, toughness and increase fracture energy [5,6]. The addition of fibers such as carbon fiber, steel fiber, polymer fiber, and rubber fiber could improve the flexural performance of concrete [6][7][8][9].…”

“…The role of fibers in the concrete mixture is considered as a reinforcement, bridging the cracks and further prevent their propagation. An excess of fibers should not be used because a large number of fibers caused poor fiber dispersion and fiber balling, leading to the reduction of the efficiency of fibers [5,6]. Meanwhile, the low content of fibers was recommended due to the influence of aggregate size on fibers in the concrete mixture, leading to the reduction of workability as well as generation of the balling phenomenon [6].…”

“…Functionally graded concrete was applied in many projects such as skateboarding areas, river tunnels, piers, etc. [5]. Based on the recommendation of previous studies [4,5,[10][11][12][13], the replacement of OPC with Fa at 20% by mass of cementitious materials and the addition of polypropylene fiber at 0.3% by volume of concrete were carried out in this research to reduce the use of OPC as well as improve the flexural performance of FGC.…”

The present research aims to investigate the influence of the ratio of reinforced concrete layer height to total height (h/H) on the mechanical properties of functionally graded concrete (FGC) containing fly ash (Fa) and polypropylene (PP) fiber. All FGC samples were prepared with a constant water-to-cementitious materials ratio of 0.36 and ordinary Portland cement was replaced with Fa at 20% by mass. The reinforcement layer of FGC was enhanced with PP fiber inclusion (0.3% by volume of concrete). The effect of various h/H ratios of 0.25, 0.50, and 0.75 on the mechanical properties of the FGC samples was evaluated. The results show that flexural strength, flexural toughness, and compressive strength values of the FGC with PP fiber were higher than those of FGC without PP fiber at the age of 28 days regardless of Fa replacement. The experimental results also pointed out that the FGC samples prepared using an h/H ratio of 0.50 were beneficial in terms of mechanical properties.

The fabrication process of polymer fibers has been analyzed in various ways, and several studies have been conducted to develop new processes and optimize existing ones. Several studies have been conducted on the electrospinning process, which can easily fabricate nanofibers, and the development of materials manufactured through electrospinning has also been investigated. However, research on the nanofiber fabrication and processing of thermoplastic polymers, such as polypropylene (PP), polyethylene and polyethylene terephthalate, is relatively lacking. Therefore, research on nanofiber fabrication is essential. In this study, PP fibers were successfully manufactured through a melt electrospinning/blowing process, which combined melt blowing and electrospinning. To analyze the melt electrospinning/blowing process, the dynamic behavior of the spinning process was observed using a charge‐coupled device camera in real time, and the effects of the different spinning conditions were compared and analyzed. As the hot air or high voltage was increased, the spinning jet area tended to increase. In addition, the average diameter of the fabricated fibers tended to decrease as a high voltage was applied at a hot air pressure of 0.01 MPa; conversely, the average diameter tended to increase at a hot air pressure of 0.03 MPa. A similar trend was observed for the tensile stresses in the PP web fabrics. The polymer fibers produced by this melt electrospinning/blowing process can be applied as a production process for nanomembranes, filters and battery separators. © 2022 Society of Industrial Chemistry.
