ACI technical committee Chairs are expected to attend this breakfast workshop to meet with fellow Chairs, TAC members, and ACI staff to hear updates on important recent developments of interest to ACI technical committee Chairs. There will be table discussions and short presentations. If you are unable to attend, please ask the Secretary of your committee or another committee member to represent you in your absence. Attendance is by invitation only.
There is no question that COVID has permanently changed how people interact in collegiate and professional settings. Zoom, Slack, and Teams have become the norm and have changed the meaning of being “present.” A three-person panel will lead a discussion on the importance of communication to re-engage professionals and students with the industry and instructors. Attendees will hear perspectives from a university faculty member, a university student, and a concrete industry professional. The speakers will share current best practices, lessons learned in their career, and strategies adopted post-COVID-19 that they have seen succeed in the classroom, profession, and during professional interactions. The learning objective is to discuss the application of these practices in order to improve the communication and engagement skills of students and professionals.
Speakers:
- Dimitri Feys (Faculty at Missouri S&T)
- Erin Stewartson (Student at Ohio State)
- Joe Clendenen (LafargeHolcim)
Chapter Officers are invited to come and enjoy a delicious hot breakfast, while networking with peers from around the world. A special guest speaker, Gary Cornillie, Vice President of Hylant, will be available to answer any general liability and optional insurance questions.

Learn how you can participate in advocacy and outreach to help ACI achieve its mission and safeguard the public. It does not suffice to have ACI committees develop standards and related programs and services without a clear path for advocacy. Standards and relevant programs must be integrated into general building codes, standards, rules, and regulations. There is no mechanism for this to occur without active engagement by ACI members and staff. Adopting agencies, authorities and ministries need to be made aware of the ACI products, educated about the benefits to their respective constituents, and provided enabling language and support materials. For standards and products intended to safeguard the public, it is an obligation of our professional society to ensure, to the extent possible, all benefit from the valuable minimum requirements developed by ACI technical committees. There's a role for all ACI members, you don't need to be a code expert or consultant - there is support from staff and through collaboration.
Learning Objectives:
(1) Review the International Code Council mode code development process;
(2) Investigate the differences in in-state and local code development;
(3) Evaluate how to participate in code development;
(4) Describe specific roles by ACI members engaged in code development.

Title: Celebrating the Faces Behind the Concrete Code
Do you remember mixing concrete, making cylinders, and using the ASTM procedure to find the splitting tensile capacity? What about using ACI 318 to find the shear capacity of a beam you were designing? These codes were all written so long ago by the giants in the concrete field, nothing has changed over the years, right? This could not be further from the truth! The reality is that there is a diverse group of students, academics, and industry members from all over the world working to move our field forward – to reflect on building failures we did not expect, to integrate high performance materials and methods that have just come to the fore. The lunchtime presenter will share with you some of the dynamic stories of people behind the code and celebrate their process of creating change. The next time you open your codes you will see beyond the equations and think of them – plus your own opportunity to make your mark on the future of concrete. The codes are a living document, and all of us together, are its authors! All are welcome to the student awards program. Preregistration is not required to attend. Following the lecture, the results of the student competition will be announced. For additional information on the ACI Competitions, please visit www.concrete.org/students/studentcompetitions.

Carbonation-cured cements, or cements that set by carbonation rather than hydration, have gained significant attention in recent years. Briefly, carbonation curing is the solidification reaction that occurs when calcium silicates (e.g., alite and belite) are exposed to concentrated CO2, forming mainly calcite and calcium silicate hydrates. The carbonation curing process was demonstrated as early as the 1970s; however, the cost of producing CO2 gas and the negative association with weathering carbonation prevented any meaningful progress. Recent interest in these materials is mainly driven by industry-wide efforts to decarbonize concrete. Proponents of the technology envision its use to produce a carbon-neutral or carbon-negavtive concrete. They suggest that the uptake of CO2 during the curing process can offset the carbon emissions embodied by calcination, and that carbonation curing is a sustainable alternative to steam curing. Meanwhile, critics point to the limitations of carbon capture technology as a critical weakness in carbonation-curing. They claim that carbonation curing often fails to produce a net reduction in embodied carbon due to the emissions associated with the capture, transport, and use of CO2.
Learning Objectives:
(1) Differentiate between carbonation curing and hydration as it pertains to cement solidification;
(2) Explain how carbonation curing can potentially support the development of carbon-neutral or carbon-negative concrete;
(3) Discuss the limitations of carbon capture technology and how they affect the development and practical adoption of carbonation-cured materials;
(4) Identify avenues for future work that will help propel carbonation-cured cements toward practical adoption.
