Experimental Investigations On Fiber Reinforced Concrete For Sustainable Construction

Abstract

:  The use of fibers to strengthen tension-weak matrices dates back over 4500 years. Since the rise of Portland cement concrete, fibers have been added to improve strength and prevent cracking, though progress in fiber reinforcement was slow until the 1960s. Typically, fibers like steel and glass are used to enhance concrete’s durability and crack resistance. This project evaluates the compressive strength of aramid fiber-reinforced concrete at 3, 7, and 28 days, comparing it to regular and other fiber-reinforced concretes (M20 grade). While steel fibers offer the highest strength, glass fibers resist cracking, and aramid fibers provide strength and crack resistance. Fiber-reinforced concrete is now widely used in slabs, shotcrete, panels, precast items, seismic structures, repairs, and more. This study highlights aramid fibers’ integration, particularly in innovative concrete applications.
