scope:

This document provides information on fiber-reinforced shotcrete using synthetic and steel fibers. Topics covered include materials used, mixture proportions, production of shotcrete, testing procedures, performance of FRS, design considerations (including an example in the Appendix), specifications, and some examples of applications.

Introduction

Fiber-reinforced shotcrete (FRS) is mortar or concrete containing discontinuous discrete fibers that is pneumatically projected at high velocity onto a surface. Continuous meshes, woven fabrics, and long rods are not considered as discrete fiber-type reinforcing elements in this guide.
