This study examines how high temperatures affect reinforced concrete, focusing on changes in compressive strength, stress-strain behavior, and steel-concrete bond slip under steady heating. Damage occurs at small scales due to concrete spalling and steel elongation. The research also reviews bonding between ultrahigh-performance concrete (UHPC) and normal concrete (NC), considering factors like surface roughness, fiber type, moisture, and curing conditions. Coconut shell as a lightweight aggregate is tested, showing bond strength higher than typical standards. Additionally, the influence of fly ash and polypropylene fibers on concrete’s fresh properties, strength, and durability is studied, with a 15% fly ash and 0.12% fiber mix yielding the best results. The work offers practical insights into improving concrete performance at high temperatures and enhancing reinforcement bonds.
