Awarded categories include: the ACI Concrete International Award, the ACI Symposium Volumes Award, the Mete A. Sozen Award for Excellence in Structural Research, the Wason Medal for Materials Research and the Wason Medal for Most Meritorious.

Comparison of Corrosion Service Life Models (ACI Fall 2023, Boston, MA) Various codes, standards, guidelines, and engineering tools (both open source and proprietary) exist to assess the service life duration of reinforced concrete structures exposed to environmental conditions that promote chloride-induced reinforcement corrosion. In this session, several of these tools will be implemented on theoretical structural components located in Boston with a required 100-year service life, including a bridge deck, a marine pile and a marine wall constructed from one of three prescribed concrete mix designs. In this presentation, the implementation and conclusions of the probabilistic-based modeling approach presented in the fib Bulletin 34 and prescriptive requirements from AASHTO Guide Specification for Service Life Design of Highway Bridges will be described.
