Shotcrete for Expedient Structural Repair

Abstract

Shotcrete, or pneumatically applied concrete, is presented as a method for expedient repair of structures in a postattack environment. A brief history of shotcrete is presented, along with a description of the two main processes, dry-mix and wet-mix. Engineering properties of shotcrete are discussed, along with methods for evaluating those properties. Special shotcrete mixtures are discussed, and fibrous shotcrete is presented a good material for structural repair because of its combination of high flexural strength and ductility. Automated shotcrete equipment is discussed and a concept for a Mobile Automated Shotcrete Expedient Repair Vehicle (MASERV) is presented. Specific recommendations are made for a proposed field test, as well as general recommendations for future research on shotcrete.
