“…Therefore, it was analyzed upon performing the compressive strength on the specimens that the masks were holding the fragments of concrete and helped the concrete fragments to adhere even upon failure. Therefore, upon adding face masks to concrete, the resultant concrete mix showed better resistance towards cracking and improved performance of the resultant concrete [14]. The following graph was formed from the compressive strength values collected in the laboratory (Fig.…”

“…The addition of fiber such as polypropylene fiber, polyethylene fiber, and so on into the concrete has been a new concept recently [14], Addition of such fibers to concrete help to improve the uniformity of the mix, strength, and durability [14]. It also helps in improving properties such as reduction in shrinkage cracks and helps in improving wear resistance, impermeability, and tensile strength of the resultant matrix [14]. The polypropylene fiber in disposable face masks contributes significantly to the tensile strength of the face masks [15].…”

The COVID-19 pandemic has resulted in the excessive use of personal protective equipment used by people to safeguard them from contracting viruses. The use of plastic gloves and face masks has raised environmental concerns. The undue accumulation of this personal protective equipment has resulted in the degradation of land and water and contributed to the spread of the virus. Thus, this research paper is divided into two parts. The first phase entails completing thorough literature research to compile data on the mechanical, chemical, and physical properties of face masks. The second phase involves the potential reusing of face masks as an additive in concrete. This study’s findings can have a significant implication for the construction industry concerning environmental pollution management. This paper also highlights the effects of improper disposal of these face masks in terms of health and safety to the common public. Moreover, the study’s results can encourage further research on the potential application of face masks in other construction materials, leading to the development of more environmentally friendly building materials.

“…In recent years, the application of synthetic organic fibers, represented by polypropylene fiber (PPF), has made great progress. Song et al [18] conducted an experimental study on the mechanical and flexural properties of polypropylene fiber-reinforced concrete, and the results showed that the fibers can inhibit crack expansion and avoid brittle damage when cracks appear in the concrete. Yao et al [19] investigated the mechanical properties of polypropylene fiber-reinforced concrete, and the results showed that the flexural strength, tensile strength, and fracture toughness of polypropylene fiber-reinforced concrete were significantly higher than those of ordinary concrete.…”

In this paper, the influence of different fiber materials on the dynamic splitting mechanical properties of concrete was investigated. Brazil disc dynamic splitting tests were conducted on plain concrete, palm fiber-reinforced concrete, and steel fiber-reinforced concrete specimens using a split Hopkinson pressure bar (SHPB) test device with a 100 mm diameter and a V2512 high-speed digital camera. The Digital Image Correlation (DIC) technique was used to analyze the fracture process and crack propagation behavior of different fiber-reinforced concrete specimens and obtain their dynamic tensile properties and energy dissipation. The experimental results indicate that the addition of fibers can enhance the impact toughness of concrete, reduce the occurrence of failure at the loading end of specimens due to stress concentration, delay the time to failure of specimens, and effectively suppress the expansion of cracks. Steel fibers exhibit a better crack-inhibiting effect on concrete compared to palm fibers. The incident energy for the three types of concrete specimens is roughly the same under the same impact pressure. Compared with plain concrete, the energy absorption rate of palm fiber concrete is decreased, while that of steel fiber concrete is increased. Palm fiber-reinforced concrete and steel fiber-reinforced concrete have lower peak strains than plain concrete under the same loading duration. The addition of steel fibers significantly impedes the internal cracking process of concrete specimens, resulting in a relatively slow growth of damage variables.

“…The incorporation of short fibers and electronic wastes has a significant benefit over the overall performance of conventional concrete like tensile strength, compression strength, durability, load bearing capacity, and post crack. (1)(2)(3)(4)(5)(6) Also, a poor tensile and flexural response of the geo-polymer concrete composites (7) and Cement-tailings matrix composites (CTMC) (8) can be enhanced with the inclusion of natural and synthetic fibers. The banana skin power (BSP) as cement replacement and coir fiber (CF) as filler in self-compacting concrete (SCC) showed enhancement up to 7% in compression strength for 0.4% of BSP and 0.5% of CF adding in SSC.…”

Objectives: To investigate the combined effect of filler and Fiber Reinforced Polymer (FRP) wrapping on the compression and flexural behavior of concrete beam structure. Methods: In this study, High-Density Polyethylene Fiber (HDPE) is used as filler in concrete ranging from 0.5 to 3% in the M30 grade concrete. The Basalt and Geotextile FRP mats were wrapped on to the concrete beams to estimate the influence of HDPE filler and fiber wrapping on compression and flexural strengths. Findings: The addition of 0.5 % and 1% of HDPE fillers in M30 grade concrete has a significant impact on compressive strength by up to 6% and flexural strength by 20% when compared to conventional concrete. Improvement: Wrapping concrete beam samples with Basalt and Geotextile fiber along with HDPE fillers exhibits an increase in compressive strength by 30% and Flexural strength by 60% with respect to pristine concrete beam samples. Novelty: Inadequate studies were found on the effect of filler and FRP wrapping on the compression and flexural strength of concrete beams. Hence, a new method of avoiding the complete failure of concrete beams by adopting a filler/fiber wrapping technique to enhance the load-carrying capacity in the concrete. Further, a greater attention was made through morphological studies to know the cumulative effect of both constituents on the strength of concrete samples.
