The ACI 506.1R-08 standard is titled "Guide to Fiber-Reinforced Shotcrete" and it provides a comprehensive overview of the technology and applications of fiber-reinforced shotcrete (FRS). The guide focuses on the use of synthetic and steel fibers to enhance the mechanical properties of shotcrete, such as toughness, impact resistance, and flexural strength. It also highlights the additional benefits of FRS, such as controlling shrinkage cracking.

The guide covers various aspects of FRS, including proportions of typical mixtures, batching and mixing procedures, and application methods. It includes information on reducing rebound, which is the amount of shotcrete material that does not adhere to the surface being sprayed. Additionally, the guide describes the different equipment used for applying FRS.

The applications of FRS are discussed in detail, encompassing a broad range of construction projects. These include rock-slope stabilization work, tunnel and mining lining construction and repair, fire and explosive spalling-resistant linings, channel linings, pools and rockscapes, and structure repair.

The guide briefly touches upon the available design information for FRS and provides a list of design references for further study.
