Advancements and Applications of Polypropylene Fiber: A Review of Properties, Processing, and Performance.

Abstract

Study investigates the impact of lengths of polypropylene fibers on the strength characteristics of M25-grade concrete. Polypropylene fibers are widely used in concrete to improve tensile strength, crack resistance, and durability. In this research, fibers of different lengths (specify lengths, e.g., 12 mm) were incorporated into the M25 concrete mix to evaluate changes in compressive, tensile, and flexural strengths. Concrete specimens were prepared, cured, and tested according to standard procedures, and results were compared with control samples without fibers. The findings indicate that certain fiber lengths significantly enhance specific strength properties, while others may not have a substantial effect. The optimal fiber length for maximizing strength performance is identified, offering insights into the practical applications of fiber-reinforced concrete in construction. This study contributes to understanding how fiber length can be optimized to improve the structural performance of M25 concrete for different engineering applications.
