Like concrete, Shotcrete poorly performs when subjected to tension; therefore, it experiences displacements and breaking when it is exposed to tensile loadings—adding fibers to concrete increases the ductility of Shotcrete. For this reason, two shotcrete mixes were prepared, plain, and reinforced with fibers (Fiber Reinforced Shotcrete, FRS). The results were looked at and recorded. Shotcrete with a strength of more than 35 MPa were designed and prepared. Steel and polypropylene fibers of different weights and shapes are added to Shotcrete. After adding fibers to Shotcrete, Shotcrete with fascinating properties is produced after testing the samples for 7 and 28 days. The results stated that the tensile and compressive strength of Shotcrete enhanced with additional fibers. Shotcrete has indistinguishable properties compared to concrete, and adding of polypropylene fibers up-to 3kg/m3 disclosed a nearly 20% rise in the compressive strength of Shotcrete. The compressive strength diminished with an increase in the quantity of fiber past 3kg/m3. The tensile and flexural properties of Polypropylene Fiber Reinforced Shotcrete (PFRS) continued expanding with higher fiber quantity. Similarly, the compressive, tensile, and flexure strength of Shotcrete increased with an increase in the number of steel fibers.
