“…The maximum voids were found at the interfacial transition between cement paste and fibre or coarse aggregate. It is evident from the result that the volume of pores is proportionate to the fibre volume fraction (7). The durability of concrete made with polypropylene, glass, and hybrid fibre was studied by rapid chloride penetration and rapid chloride migration test.…”

The Fibre reinforced concrete (FRC) has become popular in construction industry in last few decades. Various natural and artificial fibres are added in concrete to enhance the crack resistance property by developing some bonding between fibre and concrete. FRC is not only performs better than conventional concrete but also the fibre reinforced concrete (FRC) has become popular in construction industry in last few decades. FRC is not only performs better than conventional concrete but also it reduces environmental pollution. Actually in many rural area, people are not concerned about the pollution and hygiene. The unused portion of sugarcane fibre, banana fibre, jute fibre are thrown into pond/ lake. After few days they decompose and rotten, that causes pollution in waterbody and disturb the ecosystem. The fibres can be used as additive in concrete to enhance their overall performance as well as to reduce environmental pollution. In this paper, a state-of-art review has been investigated on FRC and its different benefits. Different fibres such as jute fibre, coconut fibre, polypropylene, basalt, areca leaf, glass, mask, plastic, carbon and steel fibre were incorporated in concrete by several researchers in the past decades that have been highlighted in detail in this paper. The performance has been evaluated in terms of load displacement hysteretic pattern, stiffness, ductility, energy dissipation, crack resistance, durability and workability of FRC. The virtue and limitations of FRC have also been discussed. From the existing literature, it is found that the performance of FRC under dynamic load, Damage assessment, Time dependent assessment of damage, Effect of fibre in high-performance concrete (HPFRC) and Life cycle assessment are found as major literature gap that needs to be fulfilled. A case study on damage assessment of FRC has also been conducted in this paper. From the result it is found that the Carbon fibre reinforced concrete (CFRC), Steel fibre reinforced concrete (SFRC) and Areca leaf sheath fibre reinforced concrete (ALSFRC) are experiencing lesser damage in compared to normal concrete without fibre. Based on the existing literature the future scope and probable direction of research of FRC have also been highlighted.

“…But the effects of polypropylene fibres in different shapes and distributions are well noticed. A study examined whether polypropylene fibres improve prestressed concrete durability, water absorption, capillarity, and resistance against sulphuric acid and magnesium sulphur salt solutions [16][17][18].Studies on the flexural toughness of concrete mixtures, including steel-fibre reinforced, plain high-strength, and steel-polypropylene fibre concrete, have also been conducted. According to the study's findings, steel-polypropylene fibre improves deformation performance, toughness, and strength [19][20].…”

The current study investigated the performance of rubber concrete by fully replacing coarse aggregate with construction-demolished waste (CDW) and fine aggregate with natural sand (NS) and recycled sand (RS) by using polypropylene. The test samples were prepared with CDW, NS, RS, and an addition of polypropylene (PPF) at various percentages, such as 6%, 8%, 10%, and 12%. This study examines the enhancing properties of concrete mix, such as compressive strength, tensile strength, flexural strength, and fracture analysis of concrete mix. Further, the study also focused on the elements in the concrete mix and its microstructure arrangement, which were evaluated using a scanning electron microscope (SEM). The study concludes that the higher compressive strength, tensile strength, and flexural strength at CDW-100%, RS-90%, and 10% replacement of PPF are 28.76 Mpa, 2.06 Mpa, and 2.5 Mpa, respectively. In the other case, the maximum strength was obtained with the replacement of 8% of PPF along with 92% of RS. The study addressed the higher compressive strength, tensile strength, and flexural strength at 28.92 Mpa, 2.26 Mpa, and 3.1 Mpa, respectively, at 8 percent PPF. The SEM tests were conducted to determine the combination of cementitious paste and the structural arrangement of the concrete mix with polypropylene fibre. The study results show better performance and understanding in making use of CDW and CR in pavement application. The study indicated the effective utilisation of waste material in pavement structures while reducing environmental concerns.

“…Concrete's interior is readily penetrated by water or other damaging ions, which hastens the concrete's degeneration [37]. Concrete may generate a three-dimensional random distribution network structure when polypropylene fiber is introduced, which successfully prevents the formation of microcracks [38].…”

A Review on Failure Modes and Cracking Behaviors of Polypropylene Fibers Reinforced Concrete

et al. 2022

Despite being strong under compression, concrete is rather weak when subjected to tensile stress. Concrete has been reinforced with a variety of materials over time in order to resist tensile stresses. Among various types of fibers, polypropylene fiber, which is available in a range of sizes, is being used to strengthen concrete. The fiber also increases the concrete’s toughness, durability, and low permeability. Polypropylene fibers may be utilized in place of conventional reinforcement, according to a number of researchers. The aim of this study is to collect information from already carried out research on polypropylene fibers. Important characteristics of concrete, such as workability, compressive, tensile, and flexural strength, are reviewed. The review also explores cracking behavior and failure modes of polypropylene fiber reinforced concrete. Furthermore, durability aspects, such as water absorption, porosity, dry shrinkage, and microstructure study (scan electronic microscopy), were also reviewed. Results indicate that polypropylene fiber improved the mechanical strength and durability of concrete (particularly tensile capacity) but decreased the flowability of concrete. The optimum dose is important, as a higher dose adversely affects strength and durability due to a lack of flowability. Scanning electronic microscopy results indicate that the polypropylene fibers restrict the propagation of cracks, which improves the strength and durability of concrete. The review also indicates that shrinkage cracks are considerably reduced with the addition of polypropylene fibers. Finally, the review also provides future research guidelines for upcoming generations to further improve the performance of polypropylene fibers that reinforce concrete.
