Title: Laboratory Study of Shotcrete
Author(s): Albert Litvin and Joseph J. Shideler
Publication: Special Publication
Appears on pages(s): 165-184
Abstract:Several contractors and equipment manufacturers gunned test panels of both wet-and dry-process shotcretes and shipped them to the laboratory for testing. Commercial testing laboratories also sampled the freshly gunned material at the fabrication site and determined mix proportions, unit weight, air content, and gradation of the aggregate. Other mixes with a wider range of mix proportions, water-cement ratios, and aggregate size were gunned and tested in the laboratory. Data on compressive strength, modulus of elasticity, drying shrink-age, creep, absorption, resistance to freezing and thawing, and water permeability for the various samples are reported.
