Knowledge to Practice:
Giving Back to Those Who Have Served
The ACI Foundation announces its participation in a new
ACI rebate program for U.S. military veterans who obtain an
ACI certification. Thanks to a generous donation of $50,000
to the ACI Foundation from CMEC Holdings, Inc., U.S.
military veterans seeking ACI certification may qualify for a
rebate. The program provides rebates of $250 to help ease the
financial burden of earning an ACI certification in concrete
field testing, concrete construction inspection, flatwork
finishing, or one of ACI’s other 20+ certification programs.
Visit www.concrete.org/certification/veteranrebate to
see if you qualify.
You Can’t Manage What You Can’t Measure
The ACI Foundation is participating with more than 30
industry leaders to develop the Embodied Carbon in
Construction Calculator (“EC3”) tool—an open-access tool to
evaluate the embodied carbon impact of building products.
The EC3 tool is being developed under the leadership of the
Carbon Leadership Forum, in collaboration with Skanska and
key development partner C Change Labs.
“The American Concrete Institute, ACI Foundation, and the
greater concrete community have been developing industryleading
knowledge on the use of concrete in innovative and
sustainable development,” stated Ann M. Masek, Executive
Director, ACI Foundation. “With the generous support of our
members and donors, we are pleased to invest in and join the
collective in bringing the EC3 tool into practice.”
The EC3 tool is set for formal release November 19, 2019,
at Greenbuild, complete with partner demonstrations.
Recap of SDC Technology Forum 46
The Strategic Development Council (SDC) of the ACI
Foundation hosted the first Technology Forum under SDC’s
new strategic goals. The presentations highlighted
technologies and innovations such as machine learning,
robotics, and code and design influences related to highstrength
steel research. The audience learned about the use of
nonmetallic reinforcement from the viewpoints of owners,
manufacturers, contractors, and researchers in a panel
presentation format. Attendees had nothing but positive

feedback regarding the new structure of the forum, panels,
and presentations. They also enjoyed the welcome reception
on the hotel rooftop and a group dinner on the final evening.

Strengthening Bridges and Existing Concrete
Structures Using Titanium
Presented by Jill Adkins, Perryman Company
Perryman Company has been pioneering the use of titanium
in the infrastructure market since 2012. Older concrete bridges
in the United States were not designed for the current higher
legal truck load demands. When such bridges are rated
deficient, transportation departments must select replacement or
rehabilitation to ensure safe, ongoing service.
Near-surface mounted (NSM) reinforcement is often
considered as a rehabilitation solution. In NSM strengthening,
additional reinforcement in the form of bars or strips are used
to increase the shear and flexural strength of reinforced
concrete bridge girders. The additional reinforcement is
installed in grooves that are cut into the concrete at a shallow
depth to avoid the internal steel, and epoxy mortar is used to
hold the reinforcement within the groove.
Research performed at Oregon State University proved that an
innovative rehabilitation system based on the use of titanium bars
was a cost-effective alternative. The technique is unique because
90-degree hooks can be fabricated at both ends of a titanium bar,
creating a staple (a u-shaped fastener). These hooks securely
anchor the titanium bar, providing additional strength without
total reliance upon epoxy bond between the bar and the concrete.
Titanium has high strength and good ductility along with
complete corrosion resistance. It can survive in harsh
environments with little or no concrete cover and is often more
cost-effective than the competing materials in this application.
Titanium NSM strengthening has been used on several bridges,
with the state of Oregon leading the way. A design guide and an
ASTM specification are available to assist design engineers.
TyBot—An Autonomous Rebar-Tying Robot
Presented by Stephen Muck, Brayman
The construction industry is facing unprecedented labor
shortages. At the same time, the next industrial revolution,
centered around robotics and machine learning, is accelerating
in other industries. TyBot is leading this technology revolution
for the construction industry by proving that robots can
reliably, safely, and competently work together with crews
on-site using existing construction operations and practices.
