Details

TRB will conduct a webinar on Monday, August 6, 2018, from 2:00 PM to 4:00 PM ET that explores construction of mass concrete structures, such as bridge piers and other large volume placements. The presenters will discuss the reasons why it is important to control concrete temperatures in mass concrete construction projects, how to control in-place concrete temperatures, and the latest advances in post-cooling methods.  The webinar will also provide examples of concrete temperature control in various mass concrete projects in the United States.

This webinar was organized by the TRB Standing Committee on Basic Research and Emerging Technologies Related to Concrete, the TRB Standing Committee on Properties of Concrete, the TRB Standing Committee on Durability of Concrete, the TRB Standing Committee on Concrete Materials and Placement Techniques, and the TRB Standing Committee on Concrete Bridges.

Some registrants will need to pay $95 to attend this webinar.  Sign into MyTRB.org to view registration information.

Webinar Presenters

  • John Gajda, MJ2 Consulting
  • Kevin Folliard, University of Texas at Austin
  • Ric Maggenti, Caltrans
  • Celik Ozyildirim, Virginia Transportation Research Council

Moderated by:  Anton Schindler, Auburn University

Webinar Outline

  1. Thermal control plans for transportation infrastructure
  2. Mechanisms and measures to prevent delayed-ettringite formation (DEF), which is the expansion and cracking of concrete associated with the delayed formation of the mineral ettringite.
  3. Use of post cooling techniques on Caltrans mass concrete projects
  4. Requirements and construction of mass concrete projects in Virginia
  5. Question and answer session

The first 90 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions. The Registered Continuing Education Program (RCEP) categorizes this webinar activity as relating to health, safety, and welfare including core technical.

Learning Objectives

At the end of this webinar, participants will be able to:

  • Understand the potential impacts of early-age concrete temperatures on thermal cracking and delayed-ettringite formation (DEF)
  • Identify means to control concrete temperatures during design and construction
  • Describe the requirements and role of a Thermal Control Plan (TCP)
  • Discuss case studies of mass concrete projects

Professional Development Hour Information

A certificate for 2.0 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual. For groups, only the person that registers and attends the session will receive a PDH certificate. Certificates of Completion will be issued only to individuals who register for and attend the entire webinar session.

Individuals registered as Florida PEs are no longer required to email TRB with your license number to report your attendance. Instead, please use your certificate that TRB provides through RCEP.net as verification of your attendance to the Florida Board of Professional Engineers.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

This webinar was developed in March 2018. TRB has met the standards and requirements of the Registered Continuing Education Program (RCEP).
