March 10 Webinar Cancelled – Rescheduled Date TBA

Presented by: Mike Thomas, U. New Brunswick  (BIO)
Time: 3:00 pm EST │ 1.5 hours duration
Pricing: $50 (Members & Non-Members)

Webinar Description:

Corrosion of embedded steel is the number one cause of premature deterioration of reinforced concrete structures in North America. Increasingly owners and engineers require contractors and producers to adopt strategies to guarantee that reinforce concrete structures will remain corrosion-free throughout their service lives (e.g. 50 to 100 years). This Webinar is designed to provide an understanding of steel corrosion in concrete and how the life of reinforced concrete can be extended through the production of durable concrete and the use of various corrosion-protection strategies. Topics covered will include:

• What is corrosion – causes and symptoms

• Role of chlorides and carbonation in corrosion of steel in concrete

• Producing concrete with high resistance to chloride penetration

• Test methods for chloride resistance (e.g. “Coulomb test” or “rapid chloride permeability test”) and what they mean

• Other options for extending the life of reinforced concrete structures (e.g. corrosion-resistant steels, corrosion-inhibiting admixtures, sealers, etc.)

• Use of service-life models (e.g. Life-365)

This webinar is intended for concrete producers, contractors, owners, and engineers involved in the design and construction of reinforced concrete exposed to chloride environments.

Presenter Bio:

Michael Thomas (Ph.D., P.Eng.) is a Professor in the Department of Civil Engineering at the University of New Brunswick (UNB) and a registered Professional Engineer in the province of New Brunswick.

He has been working in the field of cement and concrete research since 1983.

Prior to joining UNB in 2002 he had been on faculty at the University of Toronto since 1994 and previous to this he worked as concrete materials engineer with Ontario Hydro in Canada and as a research fellow with the Building Research Establishment in the UK.
 

Dr. Thomas’s main research interests are concrete durability and the use of industrial by-products including pozzolans and slag. His studies on durability have included alkali-silica reaction, delayed ettringite formation, sulfate attack, deicer-salt scaling, carbonation, chloride ingress and embedded steel corrosion. He is also active in the area of service-life modeling, and in the repair and maintenance of concrete structures. He has authored more than 100 technical papers and reports on these subjects, and is a co-author of the service-life model, Life-365.

Dr. Thomas is active on technical committees within the American Concrete Institute (ACI), ASTM, RILEM, and the Canadian Standards Association. He was a recipient of the ACI’s Wason Medal for Materials Research in 1997, the ACI Construction Practice Award in 2001 and was elected to a Fellow of the Institute in 2006.

Dr. Thomas is also the President of C&CS Atlantic Inc. and provides consulting services in the area of concrete materials, performance, rehabilitation and litigation. In 2005, Dr. Thomas and his colleague Dr. Kevin Folliard of the University of Texas in Austin formed School of Concrete Inc. to provide training courses, educational seminars and workshops for industry, government and academia.
