8:05Protect Your Concrete and Your People
in Cold Weather
Ken Hover, Professor of Civil & Environmental
Engineering, and Weiss Presidential Fellow, Cornell
University, Ithaca, New York
Keeping concrete from freezing in cold weather gets
a lot of attention in specifications and in the field, but
freezing concrete is often the least of our worries. Long
before the concrete freezes it is already in trouble: it has
already lost a lot of water to the dry Minnesota air, and
its rate of strength gain has already dropped to less than
one-fourth of the rate achieved in the laboratory moist
room. Even if the concrete doesn’t freeze, its strength
and durability can be significantly compromised. We will
discover that, when it comes to surviving cold weather,
concrete and people have a lot in common.
Ken Hover served as a captain in the U.S. Army Combat
Engineers, and was project engineer and project
manager for Dugan and Meyers Construction Co. in
Cincinnati, working on buildings, interstate bridges,
and water treatment plants. Joining THP Structural
Engineers in Cincinnati, he became partner and manager
engaged in the design of buildings and industrial
facilities. He holds bachelor’s and master’s degrees in
civil engineering from the University of Cincinnati, and a
Ph.D. in structural engineering from Cornell University.
Ken joined the Cornell faculty after winning the Exxon
Fellowship, designed to bring experienced professionals
to engineering programs at U.S. universities. He
teaches reinforced and prestressed concrete design,
concrete materials, and construction management. His
research focuses on freeze-thaw durability, mixture
proportions and ingredients, behavior and testing of
fresh concrete, and the impact of construction operations
and construction environment on concrete quality. Ken is
a licensed professional engineer in Ohio and New York
and is past president of the American Concrete Institute.
In 2006 he was named one of the “Ten Most Influential
People in the Concrete Construction Industry.”

The Future of Fly Ash
Benjamin Franklin, Technical Director, Headwaters
Resources Inc., Marthasville, Missouri
The concrete industry in the past has been driven
by engineers, architects, specifiers, producers, and
marketers. Today, federal regulations challenge the
industry “second only to water as the world’s most
consumed product.” Directed by the federal EPA, one
product under scrutiny is fly ash, a recognized beneficial
recyclable material used to enhance the properties
of concrete. This presentation covers an industry
perspective on what the future holds.
Benjamin Franklin has over 20 years in the ready mix,
masonry, cement, and fly ash materials business. He
is actively involved in ASTM & ACI with expertise in
fly ash and related by-products utilization, concrete
manufacture, cement production, and petrography of
damaged concrete, including hardened air evaluation,
X-Ray diffraction analysis, and cement clinker
microscopy.
11:00Project Specifications vs. Sustainable
Initiatives
Richard Szecsy, Ph.D, P.E., President, Texas Aggregates
and Concrete Association, Austin, Texas
Sooner or later, on one of your jobs, a big green monster
is likely to show up—a green building or sustainable
design project that uses a high-volume fly ash (HVFA)
mix design. These sustainability benefits are often
tempered by practical constructability limitations that
may exist. This presentation explores the alleviation of
these deficiencies in HVFA mixtures as well as other new
sustainability initiatives and how they may change the
concrete industry.
Richard Szecsy, Ph.D., P.E., is the president of Texas
Aggregates and Concrete Association. He has worked
internationally as a technical expert for a four billion
dollar ready mix and aggregate company, a department
head at a University, and as an independent engineering

12:45 p.m.Concrete Tolerances
Thomas Downs, P.E., FACI, President, Forensic Experts
PLLC, Minneapolis, Minnesota
No structure is exactly level, plumb, straight, and
true. Concrete tolerances are a means of establishing
permissible variations in dimension and location, giving
both the designer and contractor limits within which the
work is to be performed. Concrete tolerances in design
and construction are usually misunderstood and many
times misused, resulting in unnecessary construction
costs or unrealistic expectations. This presentation will
focus on ACI 117 publication on concrete tolerances,
how to understand them, and use specified tolerances in
the design and construction process.
Thomas Downs has over 30 years engineering practice
specializing in industrial, commercial, and residential
structures. His experience includes involvement in all
phases of structural design of building systems. He
is the past chairman ACI 362 Parking Structures and
ACI 117 Concrete Tolerances and the past president of
BKBM Engineers, as well as past president of Minnesota
Concrete Council and Consulting Engineers Council of
Minnesota.
1:30 p.m.Temperature Induced Forces in the
Wakota Bridge
Arturo Schultz, Ph.D., F.TMS (Fellow of The Masonry
Society), Professor of Civil Engineering, Department of
Civil, Environmental and Geo- Engineering, University of
Minnesota-Twin Cities, Minneapolis, Minnesota
To investigate the accuracy of current design procedures
for temperature induced forces, MnDOT Bridge 82855,
one of the two structures comprising the Wakota Bridge
across the Mississippi River, was instrumented using
vibrating wire strain gauges with thermistors. The
superstructure has five spans of posttensioned concrete
two-cell box sections, and the substructure consists
of three twin-walled fixed-flexible reinforced concrete
piers and one single walled pier fitted with an expansion
bearing. This presentation summarizes the findings from
the field measurements and compares them with various
analytical methods to evaluate the design procedures for
temperature induced forces.
Arturo Schultz holds M.S. and Ph.D. degrees in civil
engineering from the University of Illinois at UrbanaChampaign, and a B.S. degree in civil engineering from
Southern Methodist University (Dallas). He has been on
the faculty of the Department of Civil, Environmental and
Geo- Engineering at the University of Minnesota-Twin
Cities since 1996. He teaches and conducts research
in structural engineering specializing in concrete and

monitoring.
2:00Innovative Microsphere-Based
Admixture for Frost-Resistant Concrete:
A Paradigm Shift
Tate Coverdale, Ph.D., Director of Development, BASF
Corporation, Cleveland, Ohio
Charles Nmai, Ph.D., P.E., FACI, Engineering Associate/
Manager, Engineering Services, BASF Corporation,
Cleveland, Ohio
Concrete exposed to cyclic freezing and thawing needs
to be frost resistant; since the early 1930s surfactantbased air-entraining admixtures have been used to
provide this property, but not without challenges. This
presentation will focus on a novel microsphere-based
admixture for freeze-thaw protection of concrete that
eliminates the challenges associated with the use of airentraining admixtures. Topics to be covered will include
the mechanism by which the admixture functions, its
effect on the fresh and hardened properties of concrete,
and its benefits in producing concrete mixtures that are
difficult to entrain air in using air-entraining admixtures.
Dr. Tate Coverdale is director of development for the
Construction Chemicals Division of BASF in North
and South America. He is responsible for the overall
innovation portfolio including research, new product
development, technical services, and new applications in
