scope:

The scope of this guide is to present the most relevant test methods applicable to shotcrete along with recommendations for selecting the most appropriate methods and interpreting tests results.

This guide is divided into 12 chapters, ranging in content from the determination of mixture proportions to the evaluation of hardened shotcrete through compressive strength tests or nondestructive tests methods. Each section can be read independently, making this guide suitable for learning about a specific topic. Efforts have been made not only to present the testing methods available, but also to guide the reader on the relevance of each method for a testing program. The document has been written to flow sequentially; following some discussion regarding the planning of a testing program (Chapter 3), the reader will learn about testing for mixture proportions and freshly mixed shotcrete (Chapter 4). Chapters 5 through 9 are devoted to the testing of hardened shotcrete, while Chapter 10 offers insight into acceptance criteria for shotcrete. Chapters 11 and 12, respectively, offer brief introductions to preconstruction trials and the evaluation of in-place shotcrete. Pertinent references are compiled in Chapter 13.
