Experimental Investigation of Polypropylene Fiber-Reinforced Concrete Mechanical Properties and Durability

This study presents an experimental investigation on the mechanical behaviour and durability characteristics of two types of concrete: conventional concrete and polypropylene fiber reinforced concrete (PFRC). The primary objective is to examine the influence of incorporating polypropylene fibers into the concrete matrix and to evaluate how fiber addition affects compressive strength and overall performance. The experimental program focuses on comparing the strength characteristics of normal concrete with PFRC mixtures containing different fiber proportions. The findings aim to identify an optimal fiber dosage that improves crack resistance and enhances the durability of concrete structures.
