President's Memo

Spring is officially here and I am looking forward to the warmer weather and more daylight! Spring also means that ACI-IL is in the homestretch before our summer pause on monthly meetings and it also means award season. We are now accepting entries for our Excellence in Concrete Construction Awards Program. This program recognizes exceptional local concrete construction projects. There are seven categories including low-, mid-, and high-rise structures, infrastructure, repair and renovation, decorative concrete, and flatwork. If you have a project in mind that fits into any of these categories, now is the time to get that application filled out! It’s an easy application and we can help with any questions. Entries must be submitted to Joni Jones by April 14th. Please see additional details on the awards program in this newsletter and on our website.

In March, Cindy Williams presented a detailed update on 2021 Tollway construction as well as some of the ongoing concrete initiatives she’s leading.  We’d like to thank Cindy again for her contributions over the past two months and her willingness to share her expertise with the chapter. We are going to continue these virtual lunch time monthly meetings through May. On April 22nd, past ACI international president Dr. David Lange will present on his research about using superabsorbent polymers for internal curing. I know he has some exciting results to share. In May, we will be having a virtual meeting on May 20th about low compressive strength test results. This presentation is part of ACI’s Chapter Talks program. During the May meeting, we will have a raffle for ACI-IL members. The winner will be able to choose between an ACI individual membership ($259 value), ACI collection of concrete codes, specifications, and practices ($859 value), ACI university all-access digital subscription ($299 value), or ACI concrete repair digital subscription ($249 value). I know we will all be busy, especially in May, but put these meetings on your calendars now so you don’t miss them.

As always, please feel free to join our monthly board meetings and contribute. They are currently held virtually the third Thursday of each month.

Stay safe and I hope to see everyone at the virtual chapter meeting on the 22nd!

Dan Gancarz
ACI-IL President 2020-2021

Topic: Benefits of using super absorbent polymers in concrete

Abstract:  
Super absorbent polymers (SAP) are of increasing interest in the concrete industry.  SAP is delivered as a dry powder into the concrete mixer, and the particles are capable of absorbing water about 20-30 times their own weight.  The swollen SAP particles hold on to the water during mixing and placement, but give up the water after concrete hardens and after the water of convenience has been used or evaporated.  In this way, SAP functions as an internal curing technology similar to porous lightweight aggregates.  Benefits include suppression of drying shrinkage, improved durability, and more convenient curing options that can avoid steps such as burlap blankets and water sprinkler systems. SAP is particularly attractive for high performance concrete with lower w/c ratio and applications such as large flat slabs that are vulnerable to drying shrinkage cracking. This presentation will include methods to calculate dosage, lab results demonstrating benefits, and best practices for use in field applications.

Speaker:


David A. Lange, FACI, is Professor Emeritus of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign, Urbana, IL. Lange served as ACI President in 2018-19, and continues service on the ACI Board of Direction.  His past positions include Chair of the ACI Technical Activities Committee, Chair of the Publications Committee, and Chair of the Board Outlook 2030 Task Group.  Lange received the ACI Wason Medal for Most Meritorious Paper in 2003, 2018, and 2020.  Lange is a Fellow of the American Ceramic Society and he received a J. William Fulbright Scholar Award in 2013. Lange holds degrees from Northwestern University (PhD, 1991), Wichita State University (MBA, 1984), and Valparaiso University (BSCE, 1981).

As a Young Professional, is it worth getting involved in ACI-IL?

That is a great question. Joining an organization, especially a professional one, can be intimidating and complicated. ACI-IL is constantly looking for ways of easing the process to get involved within the organization. ACI-IL wants to emphasize the opportunities for young professionals to network with other peers in the premiere community dedicated to the best use of concrete. The chapter creates an opportunity with long-term benefits for young members to gain knowledge on the industry and wants young professionals to engage earlier in their careers to create a network for future experts/leaders in all areas of construction industry.

March Meeting Summary

Cindy Williams, Deputy Chief of Program Implementation for the Illinois Tollway gave a very informative presentation on upcoming 2021 work and concrete initiatives at the Tollway. The Tollway is now in the tenth year of their $14 billion, 15-year capital program, Move Illinois. The capital program has some big projects including the completed 62 miles of the Jane Addams Memorial Tollway (Interstate 90), the completed new toll route, the Illinois Route 390 Tollway, building a new tolled interstate, the I-490 Tollway, rebuilding and widening 22 miles of the Central Tri-State Tollway (I-294), and working on completing a large new interchange, I-294/I-57, to connect the interstates. There is a lot of work going on and in 2021 alone, the Tollway has 82 contracts worth an estimated $749 million that are scheduled to be awarded. To keep the industry aware of upcoming opportunities, the Tollway has a tentative schedule for professional services bulletins and a bid letting schedule posted on their website. Cindy also mentioned the Tollway’s diversity initiatives that include unbundling contracts to provide more new opportunities for all-sized firms and the rolling owner controlled insurance program (ROCIP) projects to support small and diverse businesses.

The second half of Cindy’s presentation focused on concrete initiatives. She touched on things that are newer and in projects now such as pavement sleepers to address expansion and construction joint issues they’ve seen on recent corridors, the maturity method for opening concrete pavement to traffic, the Tollway’s bridge deck latex concrete overlay specifications, Class CAL for overnight pavement patching, fast set concrete for small overnight bridge and approach slab repairs, and ultra high-performance concrete for a new application on some I-355 bridge joint header repairs. She also highlighted some recent changes to the Tollway’s concrete QC/QA requirements and some friendly reminders on her expectations. She finished her presentation by going over what her group in currently working on and what the industry will see in the next year including e-ticketing for materials, mass concrete drilled shafts, precast weigh-in-motion pavement, a new concrete mixtures special provision, and superabsorbent polymers. There are a lot of exciting things happening at the Tollway and we appreciate Cindy taking some time to share them with us.
