Wet-mix fiber reinforced shotcrete (FRS) is being widely used for ground support in civil tunnels and mining projects across North America. Quality Control of FRS production and application is of great importance to the owner, contractor and supplier. A typical quality control program includes: mix qualification, nozzlemen/equipment qualification, construction inspection and testing, dealing with any non-conformances and remediation of any defective shotcrete. A project example with project data is provided and discussed. Implementation of a proper quality control program is critical for shotcrete to meet the specified performance requirements, save costs, and improve safety.
