The combination of different types of fiber in hybrid fiber reinforced concrete (HFRC) improves the mechanical features and durability of regular concrete, marking a significant breakthrough in the area of concrete technology. In order to enhance the overall features of the concrete, HFRC is created by blending two or more different types of fibers into a single concrete mixture. HFRC finds applications in architectural panels, sewer lines, and in renovation of older buildings. Innovative and long-lasting construction projects can gain from its lightweight and sustainable and enhanced performance. This paper investigates the behavior of HFRC produced with quaternary mixes using a variety of industrial wastes. In this experimentation, hybrid fiber combinations with 0.5% + 0.5% fibers by volume fraction are planned, such as steel fiber + polypropylene fiber; steel fiber + high density polyethylene fiber; and steel fiber + basalt fiber. The quaternary blend is cement + fly ash (FA) + ground granulated blast furnace slag (GGBFS) + metakaolin (MK) at 70% + 10% + 10% + 10%, respectively.
The introduction of synthetic fibers into concrete has been instrumental in increasing its ductility, energy absorption capacity, and durability.
