October 24, 2001, South Norwalk, Conn.--Schupack Suarez of South Norwalk, CT, a division of The Di Salvo Ericson Group-Ridgefield, announces the release of the American Concrete Institute's report ACI 222.2R-01 Corrosion of Prestressing Steels. The report details case studies, field data, and various causes of corrosion of prestressing steel used in many concrete structures, such as buildings, bridges, parking garages, tanks and ground anchors. The report goes on to recommend protective measures against corrosion in new construction, as well as field evaluation procedures and remediation techniques for existing construction. Morris Schupack, P.E., a the senior member of the four-member subcommittee of the ACI Committee 222-Corrosion of Metals in Concrete was charged with preparing the report on Corrosion of Prestressing Steels.

"Prestressing steel in concrete was introduced into the United States in the 1940s and 1950s," explains Schupack. "Corrosion problems in the field started appearing in the 1950s."

As an early pioneer in prestressed concrete his extensive design, investigatory, and material technology experience provided an overall perspective to the Committee. Schupack has applied prestressed concrete technology to projects such as storage tanks, ground anchors, nuclear containment vessels, bridges, buildings, dams, pipes and more. In fact, fourteen articles authored by Schupack are listed in the report as references.

"The subcommittee's goal was to present an understanding of the corrosion problems, to provide information helpful in identifying and correcting existing situations, and to prevent corrosion problems in future construction projects," says Schupack.

Schupack is a senior consultant of Schupack Suarez, a division of The Di Salvo Ericson Group Structural Engineers. He is a registered professional engineer and is the senior member of ACI Prestressed Concrete Committee, which he joined in 1957, and was the second chairman of this committee. He has served on the board of the ACI, PCI, and PTI.
