The Franklin Avenue Bridge
The Franklin Avenue Bridge is an arch bridge crossing the Mississippi River near Minneapolis and St. Paul, MN. Constructed between 1919 and 1923, the bridge has been damaged by chloride-related corrosion of the reinforcement and long-term exposure to moisture and freezing-and-thawing cycles. This article, the first of a two-part series on the restoration of the bridge, focuses on the rehabilitation aspects.
Role of Rheology in Achieving Successful Concrete Performance
Concrete rheology is introduced, and insights are provided into how rheology applies to mixture design and quality control, segregation, pumping, formwork pressure, and surface finish. Basic terminology is provided along with explanations of typical measuring instruments and testing procedures used to determine rheological properties.
Inspecting Adhesive Anchors
The installation of adhesive anchors is a critical aspect of many construction projects, and special inspection of such installations is critical for safety. Guidance is provided for inspectors of new installations as well as for engineers and inspectors evaluating existing adhesive anchor anchorages.
ACI University in the Classroom
ACI University modules and certificate programs are great tools for enhancing the learning process for engineering students. Inclusion of an ACI University certificate program as part of a university course motivates students to earn resume-enhancing certificates and teaches them about benefits of being an ACI member.
Classroom Demonstrations Demonstrated
A session titled "Classroom Demonstrations Demonstrated" was held at The ACI Concrete Convention and Exposition – Spring 2017, in Detroit, MI. Presentations were designed to inspire current and future educators to enhance student learning in their classes using active learning approaches. Presenters discussed and demonstrated models they have used as teaching aids.
2016 PCI Design Awards
The Precast/Prestressed Concrete Institute (PCI) announced the winners of the 54th Annual PCI Design Awards.
ACI Board Committee Members Thanked
These ACI members have ended terms on Standing Board Committees as of The ACI Concrete Convention and Exposition – Spring 2017. Their service to the Institute is appreciated.
