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?

Steel is a common component of U.S. infrastructure, but that steel can corrode when buried in soil, rock, or fill. Steel corrosion is estimated to cost the United States 3-4 percent of its gross domestic product every year, and it can lead to infrastructure failure, loss of lives, property, disruption of energy and transportation systems, and damage to the environment. Although the mechanisms of steel corrosion are well understood, limited data on subsurface corrosion and the inability to measure corrosivity directly make accurate corrosion prediction through modeling a challenge. When hazardous levels of corrosion does occur, it is difficult to determine whether the cause was related to site selection, engineering decisions, changes in subsurface conditions, or a combination of these factors.

This report explores the state of knowledge and technical issues regarding the corrosion of steel used for earth applications (e.g., for ground stabilization, pipelines, and infrastructure foundations) in unconsolidated earth or rock in different geologic settings. The report summarizes mechanisms of steel corrosion, assesses the state of practice for characterizing factors in the subsurface environment that influence corrosion and corrosion rates, and assesses the efficacy and uncertainties associated with quantitative, field, and laboratory methods for predicting corrosion.

The industries and experts most involved with managing buried steel should collaborate to improve multidisciplinary understanding of the processes that drive buried steel corrosion. Developing a common lexicon related to buried steel corrosion, generating new data on corrosion through collaborative long-term experiments, sharing and managing data, and developing new data analytical techniques to inform infrastructure design, construction, and management decisions are key. Industries, experts, and regulators should collaboratively develop decision support systems that guide site characterization and help manage risk. These systems and new data should undergird a common clearinghouse for data on corrosion of buried steel, which will ultimately inform better and more efficient management of buried steel infrastructure, and protect safety and the environment.
