American Concrete Institute New pubs from ACI

The American Concrete Institute announces the availability of three new publications.

334.3R-05, “Construction of Concrete Shells Using Inflated Forms,” provides information on the construction of structural concrete shells using an inflated form. The publication covers major facets of the construction process, including foundations, inflation, monitoring, and backup systems. The geometric variations of inflated forms, thickness of polyurethane foam, and mixture proportions for shotcrete are also considered.

506R-05, “Guide to Shotcrete,” offers recommendations on the applicability of shotcrete for different types of construction. It covers material requirements and application procedures, gives equipment requirements for dry-mix and wet-mix processes, explores testing in detail, and emphasizes the competence of the application crew.

“Symposium Publication 232: Punching Shear in Reinforced Concrete Slabs” contains 15 papers on punching shear in reinforced concrete slabs. It contains a report on issues related to design philosophy, code provisions, contributions of flexural and shear reinforcements, and seismic blast loads.

These publications can be ordered from the American Concrete Institute. Visit or call (248) 848-3800.
