Abstract

[...]concrete becomes less ductile when its strength is increased. [...]steel fibers or synthetic fibers are commonly used in UHPC to create ultra-high performance fiber-reinforced concrete (UHPFC) with ductile behavior and enhanced mechanical properties. The use of supplementary cementitious materials, such as fly ash (FA), silica fume (SF), and granulated blast-furnace slag (GGBS) to replace part of ordinary Portland cement (OPC) is a common practice to improve the durability of UHPC. Nanomaterials such as nano-silica, nano-calcium carbonate, graphite nanoplatelets, carbon nanotubes (CNTs), and carbon nanofibers (CNFs) are used to enhance concrete properties due to their high surface area and fineness [1,15,16]. [...]a good dispersion of CNFs is essential for higher compressive and flexural strength characteristics in UHPC.
