The American Concrete Institute has released another batch of new publications. “Symposium Publication 228: Seventh International Symposium on the Utilization of High-Strength/High- Performance Concrete” contains 96 papers presented at the 2005 Symposium. Topics include: research projects that investigate mechanical properties of high-performance lightweight concrete; properties of high-strength concrete using a high flyash content; research, development, and application of ultra-high- Industry Spotlight Association News performance concrete; and nonconventional aggregates and mineral admixtures in high-performance concrete. “301-05 — Specifications for Structural Concrete” is a reference that engineers or architects can cite in project specifications. It covers materials and proportioning of concrete; reinforcing and prestressing steels; production, placing, finishing, and curing of concrete; and formwork design and construction. Methods of treatment of joints and embedded items, repair of surface defects, and finishing of formed and unformed surfaces are also specified. Separate sections are devoted to architectural concrete, lightweight concrete, mass concrete, prestressed concrete, and shrinkage-compensating concrete. “318-05 — Building Code Requirements for Structural Concrete and Commentary” is now available in metric and Spanish versions as well as English. It contains the latest code requirements for concrete building design and construction. “332-04 — Requirements for Residential Concrete Construction and Commentary” offers a code portion that covers design and construction for castin- place concrete work for one- and two-family dwellings and townhouses. “423.3R-05 — Recommendations for Concrete Members Prestressed with Unbonded Tendons” includes suggestions for revisions and additions to ACI 318. Consideration is given to determination of fire endurance, design for seismic forces, and design for catastrophic loadings, in addition to design for gravity and lateral loads. “551.1R-05 — Tilt-Up Concrete Construction Guide” covers preconstruction planning, foundations, special considerations for slab-on-ground construction, wall panel forming and casting, panel erection, connections and repairing, and painting. These publications can be ordered by visiting www.concrete.org or by calling (248) 848-3800.
