President's Report

It is hard to believe that 2018 is almost over and the new year will be here before we know it. Our Georgia Chapter had a busy year with the Dan R. Brown Awards Program, Skipper Seminar, Scholarship Clay Shoot Fundraiser and our monthly luncheon presentations.

I enjoyed my term as Chapter President this year and am thankful for all the members, board members and volunteers that made this year a success.  I would like to welcome Justin Lazenby as our Chapter President and Kelly Roberts as our Chapter Vice President for 2019. Our Chapter will be in good hands under their leadership.

The Dan R. Brown ACI Awards banquet will be February 28, 2019. Please mark your calendars and join us as we recognize the many outstanding concrete projects in Georgia.  If you have not submitted a project, the deadline is January 14, 2019. Details can be found on our website.

I hope you will join us at our holiday luncheon on December 14th.  Our 2018 scholarship winners will have short presentations and we will celebrate the transition to our new Chapter Officers.

Happy Holidays,
Tom Pfeifer
Georgia Chapter ACI, President

Luncheon Recap

We had a lunch meeting on Friday, September 21 at the Westin Atlanta Perimeter North Hotel.  We had a good group of people in attendance.  The presentation was given by Dewayne Thomas and Ross Medlin on the advancement of porosity inhibiting admixtures and their capabilities. 

Some of the topics covered included shrinkage reduction and waterproofing.  A minimum of 3 inches thickness was required and it also worked in lightweight concrete applications.

The seminar reviewed the science behind Barrier1 as well as the rather extensive testing programs they had performed and the further testing reports expected in the near future.

In closing, 2018 Vice President Justin Lazenby thanked Dewayne, Ross and everyone for their attendance.  There were a number of questions and comments at the end.

Tuo Zhao is presenting his topic on “Novel Strut-and-Tie Models for Reinforced Concrete Structures using Multi-material Topology Optimization Approach”.  Tuo is currently a doctoral candidate in the School of Civil and Environmental Engineering at Georgia Tech. He received his bachelor’s degree in civil engineering from Dalian University of Technology, and his master’s degree in structural engineering from the University of Illinois at Urbana-Champaign. His major research interests are in nonlinear and multi-material topology optimization, plasticity analysis, multiscale metamaterials, and advanced manufacturing (3D/4D printing).

2018 Robert H. Kulman Student Scholarship Winner Qingxu (Bill) Jin

Scholarship Clay Shoot

On Friday, November 9, 2018, The Georgia Chapter of ACI hosted the 3rd Annual Scholarship Clay Shoot at Etowah Valley Sporting Clay Park, Dawsonville, Georgia.It was the third annual edition of this event with excellent food and lots of fun with indiscriminate shooting of airborne objects! Each year this event has increased in size, partially due to the excellent venue and also the excellent BBQ Lunch, sponsored by LafargeHolcim, Lehigh Cement and TEC Services. The BBQ was the creation of head ACI chef Steven Maloof and his mobile assault smoker!

Wayne Wilson and Derek Brown provided a lot of assistance on the preparation, and all three got two rounds of applause from the over 50 participants that came out in such bad weather! Our First and Second Place trophy winners were Thomas and Argos respectively, so congratulations to both teams.

I really appreciate you all for making this year so successful and if I didn’t get a chance to thank you personally, I apologize! I would also like to thank all our sponsors that participated, Uzun+Case, Argos, LafargeHolcim, Buzzi Cement, Precision Concrete Summit Construction were all full stand sponsors, with Metromont, Martin Concrete, Enrst/Euclid as half stand sponsors. You helped make this event happen!

Next year is already in the works and will be in November again! I look forward to seeing all of you there next year!

George H. Harrison - Event Chairman

Thomas Concrete won first place and Argos claimed second.

Outside the Cylinder

“Earliest Known Concrete?”


Mount Vesuvius overlooking the ruins of Pompeii

During the Barrier1 presentation in November, they mentioned an ancient slab from 7,000 BC and that got me wondering what was the oldest concrete?

According to an October 2017 Popular Mechanics Article “The Rock Solid History of Concrete” by Jonathan Schifman, the oldest known use of limestone was the Gobeki Tepe temple in Turkey, dating to 12,000 years ago.

There is only speculative evidence that the ancient Egyptians may have used a little concrete and no evidence the Greeks did.  The Minoans of Crete (a cultural cousin of the Greeks) did use a mixture for floors that was similar to concrete according to a book by Robert Courland.

Somewhat surprisingly, the article places the first use of concrete, as we know it, in the hands of the Romans. We have reviewed Roman concrete in several past Out of the Cylinder articles, so we will not get back into it here.

Concrete International Magazine Article

This month in Concrete International…..Reprinted from the December, 2018 (V. 40 No. 12) issue of Concrete International with permission from American Concrete Institute (www.concrete.org)

Constructability of Post-Tensioning Anchors in Shear Walls

This article presents several different scenarios for anchoring post-tensioning cables near to or in walls and the cost, schedule, and performance implications.

The article was written by three authors from the construction side and has several ideas worth considering.
