Abstract

Fiber Reinforced Concrete (FRC) has gained recognition as a highly impact construction material due to its enhanced durability and superior mechanical properties. This research focuses on the incorporation of carbon fibers into cementitious matrices to enhance the composites’ toughness, tensile strength, and resistance to cracking deformation. Carbon fibers, noted for their exceptional strength-to-weight ratio and lightweight characteristics, have garnered considerable interest across multiple industries. This study conducts comprehensive assessments of the compressive, tensile, and flexural strengths to evaluate the mechanical properties of carbon fiber reinforced concrete (CFRC). The results demonstrate a significant enhancement in the strength characteristics of the composites with the addition of carbon fibers. In particular, there are notable improvements in flexural strength. The study also examines the impact of varying fiber lengths and concentrations on the performance of CFRC, providing valuable insights into the optimal fiber parameters needed to achieve maximum mechanical properties. These findings underscore the potential of CFRC as a viable alternative to conventional concrete reinforcements, offering improved durability and performance for construction applications.
