عنوان انگلیسی Review on the Impact of Nanoparticle Additives on Fiber Adhesion in Ultra-High Performance Concrete for Corrosive Traffic Environments
چکیده انگلیسی مقاله Ultra-high-performance fiber-reinforced concrete (UHPFRC) is a cutting-edge material in traffic and road engineering, combining fibers and cement to deliver exceptional strength and durability. Distinguished by its fine-grained composition, UHPFRC forms microscopic pores that effectively impede the ingress of water, gases, and chlorides. With an optimized mix design, UHPFRC can achieve compressive strengths exceeding 200 MPa and tensile strengths surpassing 20 MPa, along with remarkable tensile performance encompassing both hardening and softening phases. The nanoparticle additives improve the adhesion of fibers. These attributes position UHPFRC as an ideal material for enhancing the stability and longevity of traffic infrastructure components. Despite these advantages, the widespread application of UHPFRC is constrained by the susceptibility of steel fibers to corrosion in wet and aggressive environments. This review article critically evaluates the influence of nanoparticle additives on the adhesion properties of fibers in UHPFRC under corrosive conditions. It addresses the challenges, limitations, and prospective applications of UHPFRC, offering valuable insights for design engineers to accurately estimate the ultimate bearing capacity of UHPFRC structures across diverse environmental settings.
