This webinar was co-sponsored by ASCE's Structural Engineering Institute (SEI) and ASCE Continuing Education

Instructor:  Mohammad Aliaari, Ph.D., S.E., P.E., M.ASCE

Course Length: 1.5 Hours

Purpose and Background

Deterioration to existing concrete structures occurs at a fast rate and costs billions of dollars every year. Delaying repairs or temporary and inadequate fixes make the problem worse in a short time. In most cases, it costs much more to repair the structure in a future time and, in some cases, can cause structural failure. Many engineers and contractors are not fully familiar with proper procedure and often perform repairs based on their judgment and prior experiences.

This webinar intends to be a roadmap for concrete practitioners for successful and proper concrete repair and rehabilitation projects. It reviews and discusses in detail the latest guide ACI 546R-14 (Guide to Concrete Repair). It presents an overview of entire process including surface preparation, recommendations for the selection and application of repairing materials and methods, protecting and strengthening concrete structures. This webinar is applicable to repairing deteriorated or damaged concrete structures, correcting deficiencies, and strengthening the structure.

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
