NCCACI Presents

"Concrete Cracking"

Tuesday November 17, 2020
11:00am - 12:00pm

Go-To-Meeting Webinar

Speaker:  Jerzy Zemajtis, PhD, PE


This presentation will cover various aspects related to concrete cracking. This topic is both a contentious and unfortunately, a common issue nationally. Often, the key to addressing cracking issues is learning how to properly determine the cause of the crack so it can be mitigated and prevented in future projects. Topics covered in this presentation will include:

  • Causes and control of cracking
  • Evaluation methods
  • Mitigation
  • Crack repair

Learning Objectives:

  1. Understand the significance of cracks in concrete
  2. Identify the causes and mechanisms of cracking in fresh and hardened concrete
  3. Learn about the methods used to assess and evaluate cracks
  4. Discuss crack repair considerations

This course has been approved for 0.1 Continuing Education Unit (CEU) (1 Professional Development Hour / 1 AIA LU Hour)

Certificates will be emailed to attendees about 1 week after the presentation.
