Concrete deteriorates over time, while seismic activities can also reduce the life of a structure by damaging it. It was found that the concrete hybridized with 0.75% KF and 0.75% GF (HF-G 0.75 K 0.75) had the most enhanced overall mechanical properties, illustrating its potential to be utilized in the rehabilitation of bridges and structures.Ĭoncrete is the most frequently used material in structures around the globe. The compressive strength ( f′ c), flexural strength ( f r), splitting tensile strength ( f s), and other mechanical properties, i.e., energy absorption and toughness index values, were enhanced in HPHFRC as compared to CM and HPFRC. Kevlar fibers (KF) and glass fibers (GF) with lengths of 35 mm and 25 mm, respectively, were added and hybridized to 1.5% by mass of cement to create hybrid fiber-reinforced concrete mixes. The overall aim of this research study was to produce a high-performance hybrid fiber-reinforced concrete (HPHFRC) with enhanced properties as compared to plain high-performance concrete and high-performance fiber-reinforced concrete (HPFRC) for the rehabilitation of bridges and buildings. The rehabilitation of such structures is necessary for public safety. Due to seismic activities, a lot of structures develop seismic cracks. Reinforced concrete is used in the construction of bridges, buildings, retaining walls, roads, and other engineered structures.
