44 • July 2015 www.concreteproducts.com BRIEFS ORGANIZATIONS ASTM International's A1094/A1094M, Spec- ification for Continuous Hot-Dip Galva- nized Steel Bars for Concrete Reinforcement details corrosion protection for zinc- or zinc alloy-coated rebar. "Galvanizing is a proven and effective way to protect reinforcing bar from corrosion, as it provides both barrier and galvanic protec- tion to the steel substrate, [and] increases the chloride threshold," says GalvInfo Center Director Gary Dallin. In addition to protec- tion, the unique fabrication properties of the bars A1094 covers will help minimize instal- lation and long-term maintenance costs, he adds, underscoring the standard's usefulness to precast concrete producers; state and federal agencies overseeing bridge and road infrastructure; engineering and contracting New ASTM Committee A01 standard covers galvanized rebar frms; manufacturers seeking to confrm product parameters meet specifcation. A1094 was developed under ASTM Com- mittee A01 on Steel, Stainless Steel and Re- lated Alloys, which convenes next in Tampa, Fla., during November (16-19) Committee Week.

GALVANIZER GROUP UPDATES LIFE-CYCLE COST CALCULATOR The American Galvanizers Association relaunched the Life-Cycle Cost Calculator (LCCC) at lccc.galvanizeit.org while releasing a new publication, "Costs Less, Lasts Lon- ger." The former tool automates the calcula- tion from ASTM A1068, Standard Practice for Life-Cycle Cost Analysis of Corrosion Protec- tion Systems on Iron and Steel Products, using cost data from a paint manufacturer survey. Galvanizing cost data is derived from a 2014 AGA Industry Survey. The LCCC update includes the 2014 cost data, a new design template, and user-friendly functionality. AGA launched the LCCC in 2007, updating the calculator in 2010 to include the option to evaluate duplex systems (hot-dip galvaniz- ing and paint). It allows specifiers to compare either the initial and life-cycle costs of hot- dip galvanizing or a duplex system to var- ious other corrosion protection coatings. Users input three simple forms of data about a particular project including size, service life expectancy, exposure atmosphere, infla- tion and interest; the calculator runs the ASTM A1068 equation and generates results in a customizable, printable format. In conjunction with the LCCC update, AGA released "Costs Less, Lasts Longer," which discusses the parameters of initial and life-cycle cost analyses, and provides four case studies. The LCCC was used in each to compare the hot-dip galvanized or duplex system to the paint system considered. In all four case studies, the life-cycle cost of utilizing hot-dip galvanizing is more effi- cient; in some conditions, galvanizing is more economical on an initial cost basis.
