Webinar: Compressive Strength Failures: Causes, Evaluation and Resolution

Compressive Strength Failures: Causes, Evaluation and Resolution

Date: August 3, 2022

Time: Noon – 1:00 pm CDT  

Presenters: Alf Gardiner, PE (Concrete Technical Leader & Principal Engineer – Braun Intertec) and Dan Vruno, PE (Principal Engineer – American Engineering Testing)

Registration Link: https://cvent.me/01MEOx  

Description: This presentation will provide information about what is typically done when compressive strength results are less than the design strength.

The presentation will cover:

• The reasons for the low strength
• How low strength is typically evaluated
• What resolutions have they experienced

Learning Objectives:

• 1.    Understand why compressive strengths may be lower than desired.
• 2.    Know what should be done once low strength is suspected.
• 3.    How to evaluate the low strength investigation data.
• 4.    Understand what can be done to resolve the low compressive strength issue

Speaker Bios:

Alf Gardiner, PE (Concrete Technical Leader & Principal Engineer – Braun Intertec) is based out of Braun Intertec’s Minneapolis, Minnesota office. He brings over 20 years of experience and thought leadership to help clients interpret and provide conclusions of failure mechanisms based on petrographic examinations of concrete for projects with concrete failures. He uses nondestructive testing techniques such as ground penetrating radar, thermography and impact echo to determine distress in structures.

Dan Vruno, PE (Principal Engineer – American Engineering Testing) Dan has been investigating low strength concrete for over 40 years for a concrete testing firm.  His experiences provide him with a wide range of causes, evaluation, and resolution of compressive strength failures.

Sponsors: This webinar was developed cooperatively by concrete-related associations from Minnesota, North Dakota, South Dakota and Wisconsin.  The goal of the cooperative effort is to bring a greater awareness of cast-in-place concrete to the design and construction communities via quality continuing education programs.  (MCC, NDCC, SDRMCA, WRMCA)
