Review Paper on Use of Sisal Fiber and Polypropylene Fiber in Reinforced Concrete

With the introduction of fibers into concrete, a beneficial method that has evolved to increase the mechanical and durability features of concrete products has emerged. Between the many different types of fibers, Sisal fiber and Polypropylene (PP) fiber have garnered a substantial amount of interest owing to the distinctive qualities that they possess. Sisal fiber, which is a natural fiber that is produced from the Agave Sisalana plant, is biodegradable, lightweight, and cost-effective. Polypropylene fibers, on the other hand, are synthetic fibers that provide greater resistance to chemical assault and water absorption. In this study, a detailed assessment of the mechanical and durability characteristics of Sisal fiber reinforced concrete and PP fiber reinforced concrete (SFRC and PPFRC) is presented. Our primary emphasis is on the influence that the kind of fiber, its content, its length, and its orientation have on the performance of concrete. We investigate both laboratory research and actual applications. There is also a discussion of the durability elements, which include resistance to corrosion, freeze-thaw cycles, and abrasion. According to the results, both sisal and polypropylene fibers have the potential to considerably increase the mechanical qualities of concrete, including its toughness, compressive strength, and flexural strength, as well as its durability, characteristics that include resistance to water permeability, chemical assault, and other similar factors. Nevertheless, there are still areas that need more investigation, such as the issues of fiber dispersion and the optimal fiber dose.
