Standards, Test Methods, and Guides for Shotcrete Ground Support

While shotcrete technology has been generally developed over the last millennium, the evolution of mining and tunneling methods has placed unique demands on the materials, means and methods that comprise current concepts of shotcrete systems for ground support. The industry has struggled to keep the specifications, test methods and guides (standards) relevant to the new concepts and applications for shotcrete underground. This discussion outlines the standards available currently to the industry, comment on those under development, and proposes new directions for the community writing documents to assure owners that high quality shotcrete ground support can be produced in a consistent, safe and economical manner.
