The ACI Foundation Concrete Research Council will fund a record eight research projects, its 2018 budget buoyed by a one-time, $500,000 commitment the American Concrete Institute announced earlier this year to address the industry’s growing need for such technical support. The projects and their principal investigators are:
- Pre-Standard for Performance-Based Design for Wind; Don Scott, PCS Structural Solutions
- Enhanced Ductility Reinforced Concrete Coupled Wall Systems; John Wallace, University of California, Los Angeles, and Kristijan Kolozvari, California State University
- Behavior of Reinforced Concrete Coupled Walls; Christopher Motter, Washington State University
- Shear Friction Capacity of Concrete Joints with High Strength Reinforcement; Paolo Martino and Dawn Lehman, University of Washington
- A Collaborative Study for the Development of a Standard Critical Chloride Threshold Test Method; Ceki Halman, University of Missouri
- Structural Nanomodified Concrete: An Investigation of Critical Properties; David Corr and Surendra Shah, Northwestern University
- Developing a Guideline for Life Cycle Assessment of Structural Concrete through Meta-Analysis and Harmonization; Hessam Azari Jafari and Ben Amor, University of Sherbrooke
- Guideline Development for Use of Recycled Concrete Aggregates in New Concrete; Matthew Adams, New Jersey Institute of Technology
“It is essential that the concrete industry continue investing in research, which is beneficial for effective design, quality, productivity, reduction in risk, and accelerated construction,” says ACI Foundation Executive Director Ann Daugherty. This year’s commitment from ACI, she adds, enables the Foundation to back more research than ever before.

SCC Testing Technician certification
American Concrete Institute’s newest certification program tests technical knowledge on self-consolidating concrete mixes and ability to perform five ASTM Standard Test Methods: C1610, Static Segregation of SCC Using Column Technique; C1611, Slump Flow of SCC; C1621, Passing Ability of SCC by J-Ring; C1712, Rapid Assessment of Static Segregation Resistance of SCC Using Penetration Test; and, C175, Fabrication of a Test Specimen with SCC. The Self-Consolidating Concrete Testing Technician certification program consists of written and performance exams; valid for five years, it is offered through ACI’s global network of 120-plus sponsoring groups in local practitioner communities.
“As the interest and use of self-consolidating concrete increased, it became clear to the industry that standardized test methods were needed,” says ACI Managing Director, Certification John Nehasil. “ACI and ASTM committee members developed tests to measure and monitor the fresh or plastic characteristics of SCC. Near the end of the development stage, the industry recognized the need and importance of an ACI certification program to ensure these test methods were performed correctly. If you work with and test self-consolidating concrete on a regular basis, then make sure you are certified to do the job right.” — www.whyACIcertification.org.
