President's Memo

Happy Holidays!! Last time I wrote to you all we were zooming through fall and awaiting our first snowfall, well we are still waiting for that first BIG snowfall of the season – but it seems the winter temps have moved in and are here to stay. None the less, I’ve still have been very busy wrapping up projects and I hope you all have too. I always love this time of year from celebrating the holiday with family and friends, to making the final push at work to get everything together before taking a break to celebrate the New Year!

Last month we came together to celebrate the Holiday season and to raise money and/or toy donations to Toys for Tots. This year we decided to try a new venue, DOC Wine Bar in Lombard at the Yorktown Shopping Center and everyone seemed to enjoy the new location and buffet dinner. We were able to raise more money and toys than we did last year and create lasting memories for families in need this Holiday season!

We also had quite the light show at the Toys for Tots event this year, Ozinga was able to lend the Merry Mixer concrete truck for the evening. The truck sat out front of the event playing cheerful holiday music, accompanied by a beautiful light display for all to enjoy. Plenty of people driving by or shopping at the mall were thrilled to stop and take photos or listen to a few songs. Thank you to Ozinga for donating this wonderful experience to our event!!

Looking forward to seeing you all at our January 15th, 2020 Dinner Meeting at Gibson’s in Oakbrook. We welcome George Houston from IDOT District One, as he plans to give us an update on IDOT projects in Chicago and throughout District One for the 2020 construction season and beyond.

One quick reminder – the 2020 Spring ACI Convention is right around the corner being held right here in Rosemont. We will need a lot of volunteers for this event, if you want to get more involved or even join the board – please attend one of our open board meetings, which take place at 3:30pm before our dinner meetings.

Have a great Holiday Season and see you all next year!!

Best Wishes,
Peter J. Schroeder

November Meeting Recap

Dr. Jose Pacheco and Dr. Jan Vosahlik from CTLGroup’s Concrete and Cement-Based Materials Group discussed the goals and challenges of concrete designed for extended workability.

Jan Vosahlik explained what concrete workability means, how to design for it, how it’s evaluated, what causes workability loss, and strategies for workability retention. Jose Pacheco followed up with bridge tunnel and bridge deck case studies involving thorough laboratory and field testing which provided insight on workability issues.

Some key takeaways from Jan and Jose’s presentation included that concrete workability goes beyond slump, various strategies exist for designing for workability, and both laboratory and field evaluations are necessary.

We thank Dr. Pacheco and Dr. Vosahlik for presenting this topic to our members.

Bowling Ball Competition

FRC Bowling Ball Competition – ACI ILLINOIS


The objective of this competition is to demonstrate the benefits of fiber use in concrete, to facilitate interaction between industry professionals and student members, and to enable students to earn some money towards competing at the ACI National Convention in Rosemont, IL in Spring 2020. Each team will design and fabricate a fiber-reinforced bowling ball. These are a simplified version of the National Competition Bowling Ball Rules, to be held in the Spring 2020 in Rosemont, IL.


The competition will take place at the ACI IL facility in Elmhurst, IL on 8 February 2020 beginning at 9am. Lunch will be provided. The results of the competition will be evaluated with the winning teams awarded at the ACI IL dinner meeting on 26 February 2020 at Erie Cafe. Teams and advisors are invited and welcome to attend – registration for the dinner meeting is on the ACI IL webpage.

Competition and Prizes

The Local Competition has a two prize categories: Student Team and Industry Team. Fiber-reinforced bowling balls will be tested for size and density, the ability to be used successfully as bowling balls, and post-crack load capacity (toughness). The winning Student team will be awarded a prize of $750 to help offset their costs in representing the IL Chapter at the National Competition in Rosemont, IL at the end of March. The winning Industry team will be awarded “The ACI IL Student Competition Non-Student Traveling Trophy” – a beautiful crown, cast in concrete and weighing approximately 20 lbs. The prizes will be awarded at the ACI IL dinner meeting on 26 February 2020.
