Laboratory and Field Geotechnical Characterization for Improved Steel Corrosion Modeling
March 9–10, 2021
11:00 a.m.–6:00 p.m. (EST)
Virtual Workshop Agenda
The National Academies’ Committee on the Corrosion of Buried Steel at New and In-Service Infrastructure is hosting a 2-day virtual workshop to gather information on field, laboratory, and modeling methods for characterizing corrosion of steel buried in earth materials and new developments in the prediction and monitoring of corrosion of steel in earth applications and environments. These sessions are part of the National Academies’ consensus study examining the state of knowledge and technical issues regarding the corrosion of steel used for each application and identifying knowledge gaps and research needed to improve long-term performance of steel.
DAY 1
SESSION 1—Modeling
11:00 a.m.–2:15 p.m. EST
Identifying corrosion modeling approaches for improved understanding of corrosion potential (Ecorr), rates, assessment, and management
Session Objectives:
- Define common vocabulary for workshop participants.
- Describe current deterministic modeling approaches and their limitations.
- Identify emerging (nondeterministic) modeling approaches and challenges to their application.
Prompting Questions for Speakers:
- What do current deterministic models deliver, and with what kinds of limitations and uncertainties?
- Are there assumptions in deterministic corrosion models that are no longer needed or valid?
- What are the opportunities for improving deterministic models and what steps are needed to do so?
- What limitations and uncertainties in deterministic models can be addressed with nondeterministic models and what steps are needed to do so?
