President's Report

Happy New Year !

Well…it will be much happier when we have general distribution of the COVID vaccine and things may become more…. normal.  So far, it seems construction has been impacted less that I would have thought, so there is some good news. 

George Harrison will be our speaker for the 2021 inauguration, so we will be looking forward to that.

Unusually, the Dan Brown Awards Program will not be in February, but we will delay it until the summer this year only with the hope that we can then do it in person.

As we move into spring, it always a good time to make sure that your certifications are up to date. If you need to recertify or add to your certifications, please check the website for upcoming classes.

If all goes well, the ACI National Convention in October 2021 will be in Atlanta.  We are hoping this will be a live, in person event and not “virtual”, as most of 2020 seems to have been.  There will be updates on this later this year, as we learn more.  Importantly, there will also be opportunities to sponsor and to get event booths.

Everyone keep safe and I hope you all have good health and well-being this year.  I am hoping we will turn a corner on this.

Our Next Event

On Friday, January 29, 2021, The Georgia Chapter of ACI will open an eagerly anticipated new year with our first lunch meeting in 2021 at the Westin Atlanta Perimeter North hotel.  Unfortunately, our old friend COVI-19 is still around and you will see the same Hotel Infection Avoidance Policies in place like required face masks while moving around public spaces, socially distanced seating and individual food service. 

Long time GA Chapter Member, George Harrison, Project Manager for Non-Destructive Testing and Field Testing with SGS/TEC Services will be presenting on “Building Repurposing: Problem, Evaluation and Solutions”.  The presentation will look at different investigations that SGS/TEC has done, what the goal was, how they evaluated the in place concrete and the solutions that were provided based on their evaluation. 

George Harrison, CCSI; Project Manager for Non-Destructive and Field Testing. Manages projects of Non-destructive testing of concrete; Field Evaluations; Concrete Load Testing of Existing Structures; Bond Testing; Anchor Pull Tests; Certification of Fall Arrest Anchorages; Concrete floor slab levelness evaluations; GPR.

Luncheon Recap

“2020 Scholarship Winners and Changing of the Guard” 

Our December Lunch Meeting was a chance to farewell and good riddance to 2020; and a change to hear updates from our two 2020 Scholarship winners:

  • Daniel Benkeser graduated from the University of Illinois at Urbana Champaign in 2017 with a Bachelor’s Degree in Engineering Mechanics. During this time, he worked as an Undergraduate Research Assistant for Dr. David Lange, researching self-consolidating concrete. He received a master’s degree for Civil & Environmental Engineering from Georgia Institute of Technology in 2020 and is currently working towards his PhD as a graduate research assistant for Dr. Kimberly Kurtis. His research is focused on the reutilization of industrial waste materials to be used as a supplementary cementitious material (SCMs), an ingredient in blended concrete mixes. This research focuses on processing different sources of potential SCMs, determining their subsequent quality, and introducing different methods for beneficiating these waste materials.

 

Daniel gave us and update on the United States energy sector and its shift from coal combustion toward natural gas and other renewable energy sources.  This has affected the availability of fly ash, leading to increased interest in the identification of alternative sources of supplementary cementitious materials (SCMs). One promising option is the utilization of previously ponded or “reclaimed” coal combustion residuals, including reclaimed fly ash. His study work examines thirteen reclaimed coal ash samples for compliance with the ASTM C618 standard. These results indicate that many reclaimed ashes retain pozzolanicity, as measured through strength activity index (SAI), with nine of the thirteen ashes passing SAI requirements. Despite this, six of the thirteen samples did not meet ASTM C618 requirements, including exceeding limits on loss on ignition and particle size. For those ashes that did not meet SAI requirements, a novel and low-cost beneficiation process through chemi-mechanical grinding was examined. Processed ashes showed increases in the amorphous content by 5-36%.

 

  • Luna Al Hasani started her PhD at Georgia Tech in 2018 in the fields of structural engineering and materials science. She holds a master’s degree from the University of Sheffield in Steel Construction, and a master’s degree from Georgia Tech in Civil Engineering. Luna started her career by working in the industry as a structural designer and decided afterwards to move into research and academia. Her current research involves the evaluation of Georgia specifications regarding mass concrete, where there is a need to develop better thermal management methods. The work also includes aspects of cement hydration and cracking behavior of mass concrete structures. After graduating, Luna is interested in pursuing a position in interdisciplinary research, involving both structural engineering and concrete material science.

 

Luna gave us an update on mass concrete and the management methods needed to limit maximum temperature in concrete structures to  to control DEF, and limit maximum temperature differential in the structure to  to control cracking. The talk provided an overview of a case study implemented in Georgia and the thermal control measures that were adopted to manage heat generation, as well as discusses potential alternatives.  Moreover, a brief theoretical background with regards to the above-mentioned temperature limits imposed by GDOT was presented and gaps identified.

 

To close; out going Board Members were recognized and in-coming members installed.  Of particular note was the presentation of COVID 2020 President’s Plaque to Kelly Roberts!  Personally I hope this is the one and only COVID Plaque ever presented…

Concrete International Magazine Article

 

This month in Concrete International…..

Reprinted from the January, 2021 (V. 43 No. 1) issue of Concrete International with permission from American Concrete Institute (www.concrete.org)

This month’s article reminds me of a presentation our Past-President, Kelly Roberts gave us about two years ago on sustainability.  The article builds on the growing worldwide trend of making concrete more environmentally friendly. The article, Pilot-Scale Efforts in Reducing Embodied Carbon Footprints of Concrete in India lists notable initiatives taken by some leading professional and manufacturing organizations in relation to developing criteria for characterizing the “greenness” of concrete.  Further, the article provides a review of the current status of the concrete industry in India and recent pilot-scale efforts toward evolving and implementing green product certification in this country.
