Title: Structural Quality Lightweight Shotcrete
Author(s): Phlip D. Barnard and Robert E. Tobin
Publication: Special Publication
Appears on pages(s): 123-138
Abstract:Shotcretes weighing 90 to 120 lb per cu ft with compressive strength from 2500 to 6000 psi may be produced using fine expanded clay or shale aggregates. Economic factors influencing selection of this material are discussed, and engi-neering data necessary for design are presented. Properties of the lightweight aggregates used and proportioning of the shotcrete mix are explained. The authors also cover equipment and construction methods for applying, controlling rebound, finishing, curing, and testing the lightweight material. Construction applications in the United States are cited.
