President's Message


Well, here’s the Summer Newsletter of the Georgia Chapter ACI. So I guess I must make the obligatory reference to the hot temperatures. When it is hot, I re-read ACI 306R-10, "Guide to Cold Weather Concreting” to make me feel cooler. The workers on the construction sites do not have this luxury. They have to suffer through the high temperatures. We should thank them for making our projects come to reality.

We engineers who work in offices dread visiting construction sites during extremes in weather. (I prefer hot over cold.) One of my memorable hot visits was an east Texas jail concrete placement during summertime. The structural slab-on-ground (on void forms actually) supported by piles had a planned 10 to 11 hour concrete placement. After several hours of resolving congestion problems between reinforcement and embedded conduit the evening before, I arrived on the site around 4:00 a.m., an hour after placement started, and stayed to see the concrete finishing begin. Fortunately the building was already roofed, so sun and wind were not a factor. The contractor had ice-water barrels all around for the workers to drink from. The contractor also provided lunch for everyone, buckets of tamales.

The speaker for the May 20, 2016 membership meeting was Michael Morrison, ACI Certification Development Manager. He spoke on “New ACI Certification Programs, Now and the Future – 21 Certification Programs and Growing!” Certification and testing are very important for concrete. Concrete is mixed at a plant or on site, delivered to its site, placed, finished, and cured.  Many people “touch” the concrete in each step. Certified personnel test the concrete to verify that it meets the project requirements after going through these construction steps. 
Please see Wayne Wilson’s report for the May meeting.

I did not attend the Skipper seminar which included a visit to a quarry and a ready-mix plant.  Please see Angela San Martin’s report elsewhere in this newsletter.

It is mid-August, kids are starting back to school, and football is starting. This means GA ACI will soon be starting its monthly membership meetings after its summer break.  (I hope you went somewhere interesting.) Please see the list of fall meeting topics listed on the Luncheon Meetings webpage. We hope to see you at the September meeting.

Wilbur C. Bragg, II
Georgia Chapter ACI, President
 

GA Chapter Virgil D. Skipper Seminar Recap



 
In 1978 The Georgia Chapter of ACI established the Virgil D. Skipper Award. The award was given to promote the use of ready-mix concrete in Georgia and to honor the 30+ years of dedicated service that ACI Fellow, Vigil Skipper, gave to our industry. In 1985 Virgil passed away; that same year GA Chapter ACI Members voted to replace the Skipper Award program with an annual Virgil D. Skipper Memorial Seminar in memory of Mr. Skipper. It is in keeping with his interests and spirit that the GA Chapter presents this special program every summer.

The 2016 Seminar had 40+ attendees that included contractors, engineers, architects, manufacturers and testing lab folks for a half day orientation and seminar on the behind the scenes working of a stone quarry and a concrete ready-mix plant in Cumming, GA.  Brian MacNamara of Bluegrass Materials Co. opened with a safety presentation to the group, followed by:
  • Chad Dobbs, Bluegrass Quality Control Manager, reviewed the inner workings and daily material quality control operations that occur at the Bluegrass Cumming, GA Quarry.
  • Jeff Williams, Bluegrass Operations Manager, talked about the detailed operational activities and processes that occur each day to keep the quarry up and running. The quarry encompasses about 500 acres and they maintain two open pits for mining.
  • Kirk Deadrick, Argos Ready Mix Director of Quality, provided operational details of their on-site ready mix plant. The Cumming Plant is one of Argo’s busiest operations that regularly produces anywhere from 900 to 1500 cubic yards of concrete daily.  The plant has a state of the art central mix batching system that was design to accommodate multiple concrete types, offers excellent QC systems with electronic records control, and is capable of batching a 9 yard load of concrete in approximately 2½ to 3 minutes. The plant just recently was modified to batch carbon sequestered concrete using Carbon Cure’s CO2 dispensing system.











After our speakers finished their presentations, we loaded up in vans and all drove to the bottom of the quarry. They have about 35 to 40 men working in the quarry at any given time. Currently they are operating at approximate 400 feet down from the surface and have plans to push that to about 800 feet. Once they reach 800 feet the operational logistics of moving material to the surface become too expensive and the pit will likely be closed and reclaimed.



Following the quarry bottom visit, we split into two groups for alternating tours of the quarry rock processing operations and a walking tour of Argos’ ready mix plant and regional QC testing laboratory. Everyone had a great time and we all enjoyed a catered lunch from Jim n Nick’s BBQ.

May Luncheon Recap


We had a pretty good crowd this month to hear Mike Morrison, Manager of New Certification Programs with ACI International speak on some of the new ACI Certification Programs coming from ACI in the coming months. Click here for the presentation. Mike opened with a review of how a new certification program is proposed and developed. In short, when a new program is proposed the development process proceeds as follows:
  • A potential need is identified, this can come from inside ACI or most often the need comes from outside ACI from industry.
  • ACI has a review process in place to justify the need and establish the basis for a program; this includes an industry review to determine if a current program already exists.
  • ACI’s Certification Programs Committee (CPC) reviews the justification and either approves or denies the need to proceed.
  • ACI’s 601 Committee on New Certification conducts an industry survey and prepares a financial impact statement for submittal to CPC, ACI Finance and the ACI Board of Director’s.  If approved CPC establishes a task group of Subject Matter Experts to develop the new certification program.
  • The 601 Task Group creates a list of reference materials, develops a job task analysis, creates an exam, develops the ACI Workbook & Study Guide, hosts a pilot program to vet the exam, reviews and adjusts the exam process and pushes the New Certification Program to market.  Depending on the urgency of need this process can take 2 to 4 years to complete.
Some recently added certification programs include; Masonry Field and Lab Testing Technician and Concrete Quality Technical Manager. Mike reviewed some details and challenges experienced in developing each of these programs. Some New Certification Programs currently under development include:
  • Adhesive Anchor Installer Inspector
  • Cement Physical Tester
  • Self-Consolidating Concrete Tester Technician
  • Concrete Construction Sustainability Inspector
  • Decorative Concrete Finisher
  • NDT / GPR Specialists
Mike briefly review each new program and updated us on where in the development process each program was. Mike rapped by awarding a one year Manual of Concrete Practice subscription to one lucky member and Vice President, Wayne Wilson closed the meeting by thanking everyone for their attendance and making the speaker’s cup presentation.
 

LLS Woman of the Year 


                 

Each year, in communities across the country, dedicated candidates engage in an exciting competition to earn The Leukemia & Lymphoma Society's (LLS) "Man & Woman of the Year" titles.

Raising funds for LLS blood cancer research the candidates compete in honor of children who are local blood cancer survivors, the Boy & Girl of the Year.  Every dollar raised counts as one vote and the titles are awarded to the man and woman with the most votes at the end of 10 weeks. 

As many of you know, GA Chapter ACI Past-President, Angela San Martin participated in the 2016 competition. Angela was able to raise $199,793 for this most worthy cause. For her efforts she has been named LLS Atlanta Women of the Year! Angela wanted to thank everyone who gave money to LLS and the GA Chapter ACI says, WAY TO GO ANGELA!!
 

Concrete International Magazine Article 




This month in Concrete International…..
Reprinted from the August 2016 issue of Concrete International with permission from American Concrete Institute (www.concrete.org)



This article is part of an ACI Technical Session I will be moderating at the Fall Convention in Philadelphia, really makes you stop and think about what we mean we say “initial set” for concrete.

What Do We Mean by “Setting”?, this article provides a comparison of the stiffening behaviors of pastes, mortars, and concretes using standard tests methods and field-oriented nonstandard measures. Based on the test results, the authors determined that while the ASTM C403/C403M test provides a useful means of tracking the continuous process of stiffening, its threshold values for “initial” and “final” setting do not necessarily coincide with the times at which concrete placing, consolidation, or finishing operations must be performed.
