Abstract:

Steel fiber-reinforced shotcrete (SFRS) was first introduced into North America in the early 1970s. Since that time, it has been used in numerous applications, mainly in new construction or lining rock slopes and underground openings in mines and tunnels. There has been relatively little use of this innovative material for rehabilitation of concrete structures. Some of the mix design, batching, mixing, and placing procedures that have been successfully used in numerous SFRS projects in British Columbia are reviewed. Physical properties of SFRS that make it particularly attractive as a rehabilitation material include its good bond characteristics, flexural strength, toughness, impact strength, fatigue resistance, and durability. These characteristics of SFRS are reviewed. Existing SFRS rehabilitation projects are briefly reviewed and suggestions are made for applications where SFRS could provide a viable alternative to conventional rehabilitation procedures.
