This classic collection of 13 papers on shotcreting has been reprinted. Prepared as a guide for both field personnel who apply shotcrete as well as for engineers who specify its use, Shotcreting presents data on engineering properties of both dry-mix and wet-mix shotcrete made with coarse and lightweight aggregates as well as sand. Quality control methods and preparation of test specimens are discussed. Equipment capabilities are covered in detail. Shotcrete for repairs, use of shotcrete in tunnel linings and other underground support, shotcrete tanks, lightweight shotcrete, and the gunning of refractory castables receive attention.

Includes William R. Lorman's Engineering Properties of Shotcrete

Lorman's report supplements data on current practice in shotcreting with a review of the past 55 years of laboratory and field experience with pneumatically applied mortars and concretes. Emphasizes data on strength, elasticity and other physical properties of the hardened shotcrete. Compares properties of fine-aggregate shotcrete and coarse aggregate shotcrete and presents recommendations for mixing and testing methods.
