Abstract:
Describes the techniques of dry-mix shotcreting. Cements and aggregates for shotcrete are reviewed. Basic types of equipment manu-factured in the United States are discussed, and their operation is explained, including details of the nozzleman’s work. Sand pockets are defined, and reasons for avoiding such imperfections are given. Recommendations on the use, size, and proper en-casement of reinforcing steel are made. Bonding ability, curing, finishing, and acceptable weather conditions for shotcreting are considered. Comments are given regarding compressive strength testing and qualification of nozzlemen.
