President's Report

Summer is here. The kids are out of school which means that traffic is lighter. I hope everyone has a safe summer and can take a break for at least a short vacation.

The Georgia Chapter of ACI takes a summer break from our regular monthly meetings which will resume in September. However, we will be hosting the Virgil D. Skipper Seminar on July 12th. We will have a great presentation on the Mercedes Benz Stadium project with several members of the construction team. This seminar will be held at the stadium with a tour and lunch provided. Make sure you sign up soon to reserve your spot.

If you missed our May meeting, Jeff Speck gave a great presentation on internal curing with lightweight aggregates.


Best Regards,
Tom Pfeifer
Georgia Chapter ACI, President

Luncheon Recap

We had a lunch meeting on Friday, May 25 at the Westin Atlanta Perimeter North hotel. We had a good group of people in attendance. The presentation was given by Jeff Speck, who is the General Manager of Marketing and Technical Sales for Trinity Lightweight, the nation’s leading manufacturer of rotary kiln expanded clay and shale lightweight aggregates. Jeff covered the process of internal curing by prewetting lightweight aggregate.

Pre-wetted expanded shale, clay or slate lightweight aggregate is used in a concrete mix design to provide reservoirs of water within the concrete that slowly release the water after the concrete sets to provide internal curing to the mixture. Using a typical concrete mix, a portion of the normal weight fine aggregate is replaced with prewetted fine lightweight aggregate.

Lightweight aggregate is used for internal curing because of its increased absorption, which can range from less than 10% to more than 30% depending on the type of aggregate and how thoroughly it has been prewetted. The higher absorption enables prewetted lightweight aggregate to carry water for internal curing. The moisture is not released from the aggregate until after the concrete has set and the pore size in the paste becomes smaller than the pores in the lightweight aggregate. The absorbed water does not affect the water-to-cementitious materials ratio.

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

Celebrating the Life of Nick Maloof



Nicholas F. Maloof, Jr., age 75, of Pelham, AL, passed away on Thursday, May 24, 2018. He was born on December 31, 1942 in Pawtucket, RI.

Mr. Maloof graduated from Cumberland High School before serving in the U.S. Navy from 1960-1963. He retired in 2008 after more than 35 years in the Ready Mixed Concrete industry.

Mr. Maloof's hobbies included woodworking, cooking, reading, good cigars, telling and hearing funny stories, and "being social."  After retiring, Nick once told his son Steven that the only thing he missed about the industry was the people.  This is why he enjoyed participating in ACI locally and nationally.

He was predeceased by his parents, Nicholas F. Maloof, Sr. and Rita Maloof.

Survivors include Nicholas Jr.'s wife of 54 years, Beatrice "Trixie" Maloof; one daughter, Tina Coyle (Steve); two sons, Nick J. Maloof, Sr. (Cari) and Steven Maloof (Bebe); six grandchildren, Nicholas J. Maloof Jr., Mary Maloof, Casey Coyle, Matthew Coyle, Bailey Oakes, and Savannah Cook; four sisters, Mary Roberts, Rita Owens, Evelyn Keene, and Margaret House; and four brothers, Ronald Maloof, Raymond Maloof, David Maloof, and Joe Maloof.

It is with a heavy heart I share with you the news of the passing of a dear friend and a true legend in our industry, Nicholas F. Maloof, Jr.  Nick passed away at the age of 75 at his home in Pelham, AL on Thursday morning, March 24, 2018.

I still remember the first time I met Mr. Maloof.  It was at BEERS Construction meeting downtown; it had to have been sometime around 1987 or maybe 88?  I was a concrete field technician with ATEC Associates at the time and we were all having a meeting to discuss some recent “low concrete test cylinder” results.  I was scared to death, as I had already heard several stories about Mr. Maloof and his tendency to berate poor low level technicians who did not do their job in accordance with accepted ACI testing protocol.  It turns out that Nick was none of those things, he was just a man of conviction that always stood up for his product and only insisted that everyone do their part to see that things were done the “right way”.  Nick was a loyal supporter of our industry for many years.  Just a few of his accolades: GA Chapter ACI (President 1996 & 2006, Distinguished Member 2000), ACI International (Fellow 2003), NRMCA (Committee Chairman & Examiner) and GRMCA (Lifetime Member in 2012).

I have a few very personal memories of Nick that only a few will understand, the seafood tower with “little neck oysters” in Boston, MA; the $40 halibut lunch at Papa Does, and the safety day gear provided at no cost to the Duluth BSA Troop 419.  Nick always had a smile on his face, a good story, a good cigar in his pocket and a caring heart for those in need.  God speed Mr. Maloof I will miss you…

Services of celebration to remember Nick will be held on June 9, 2018 at 11:00 am, at Grace Christian Church, 869 Highway 52, Helena, AL 35208.  In lieu of flowers, memorial gifts may be made to the American Heart Association and/or Grace Christian Church.

The following is a reprint from the March 2003 issue of Concrete International in which ACI Honored their newest elected Fellows of the American Concrete Institute:

Nicholas F. "Nick" Maloof is General Manager of Technical Promotion for Thomas Concrete Industries, based in Atlanta, GA.  He oversees Thomas' ISO 9001 Quality Management System, as well as Thomas Concrete Academy, the company-wide training program for Thomas' U.S. operations.

An ACI member since 1984, Maloof is an ACI Flatwork Finishing Technician and Examiner, Level I Technician and Examiner, and a NRMCA Certified Instructor.  He is a member and Past President of the ACI Georgia Chapter Board of Directors, and was a Distinguished Chapter Member in 1995.  He is also a member and Past Chair of the Georgia Chapter Awards Committee and a member of the Georgia Chapter Convention Committee.

He is active in the promotion and technological advancement of ready-mix concrete and concrete materials, as well as environmental issues in the following organizations: Georgia Concrete & Products Association, of which he is Chair of the Technical Activities Committee; the Georgia Concrete Advisory Board, of which he is a member of the Board of Direction; a member of ASTM Committees C-09, Concrete and Aggregates, and C-94, Ready Mixed Concrete; the National Ready Mixed Concrete Association (NRMCA), and a member of the Civil Engineering Curriculum Advisory Board at the Southern Polytechnic State University, Marietta, GA.

Maloof studied electrical engineering technology in the U.S. Navy and at the Southern Polytechnic State University, Marietta, GA, and has 29 years of continuous training in concrete design and control and concrete technology in the ready-mix concrete industry.

Submitted by Robert Eyster:

I met Nick in 1977 or so, when he was hired to run the Williams Bros. concrete plant for the new terminal at the Atlanta Airport. I was working for WR Grace at the time and was charged with verifying the various mix designs for the job. So of course Nick would batch a mix to spec and then I would sample it accordingly. Nick would then come out side to see how the test were run. I went through slump, air, yield, temp and made the appropriate amount of test cylinders. Nick was fascinated with the procedures and asked me to explain each one. Because of the amount of mixes for the project it took several days and we became friends through the process. We did the math and adjusted the mixes one by one for proper yield. He became so interested that I gave him copies of the test procedures from ASTM and the criteria from ACI.

I did not see him for awhile after that but eventually at the ACI GA Chapter, when I learned that he had decided to pursue the quality assurance end of the business after getting started on the Atlanta Airport project.

The rest is history now with his long career at Thomas and a great supporter of ACI and ASTM as well as promotion of the concrete industry in Georgia and elsewhere.

Outside the Cylinder

“Underwater Concrete Restaurant...Really”

Construction of an underwater restaurant in Norway designed by Snøhetta is underway in Europe. The structure is being erected on a floating barge not far from the site it will come to rest. The project will also house a marine life research center. The structure will project some out of the water, presumably for entry purposes with most of the structure 16 or more feet below the surface. The restaurant’s acrylic windows (similar to the Georgia Aquarium) will allow views of the surrounding sea and wildlife.

This all sounds very much like a part of the James Bond film “The Spy Who Loved Me”, but there are no plans for a criminal mastermind to run the restaurant and hijack nuclear submarines….that we know of.

Concrete International Magazine Article

This month in Concrete International….. Reprinted from the May, 2018 (V. 40 No. 5) issue of Concrete International with permission from American Concrete Institute (www.concrete.org)

Everything is Bigger in Texas

This article is a story about a 256,000 square foot slab pour done in one large pour rather than a series of 20,000 square foot pours of a more regular size.  Barton-Mallow did this project at the General Motors Arlington Assembly Plant in Arlington, Texas.

The article covers the planning and quality control of the logistically impressive endeavor, using 600+ trucks, multiple 12 hours shifts and strong coffee.
