DuraModel Demo Version Now Available on Internet
Offers Users Corrosion Protection Alternatives and Lifecycle Cost Analysis
Cambridge, MA, November 11, 1999 - Grace Construction Products has unveiled a new interactive Internet
preview version of its DuraModel Software, a program that provides
in-depth analysis of corrosion protection alternatives and lifecycle
costs in a matter of minutes.
"Our goal is to make it as easy as
possible for users anywhere in the world to 'test-drive' the DuraModel
program by accessing a demonstration version on the Web," said Tim
Durning, Grace Construction Products.
The new web demonstration version,
which can be accessed at Grace Construction Products' web site,
www.graceconstruction.com, walks potential users through a simulated material
selection modeling process (MSMP) for a hypothetical project. It then
generates a recommended corrosion protection program based on a set of
variables that the user enters. These variables include the expected
service life of the "project," overall budget, and "project" repair
costs. The DuraModel program analyzes the information and the results
are graphically displayed in a comprehensive report that is easy to
"The science of corrosion protection can be very complex and
often confusing," Durning said. "Grace's DuraModel is an easy way to
make sense of it all."
The DuraModel program is based on a scientific
modeling process that uses Laws of Physics, standardized test
procedures, and field grade concrete testing. It then compares all
available corrosion protection products and systems - not only those
developed by Grace Construction Products - to make the most appropriate
The site also includes a
comprehensive glossary of terms and user-friendly instructions for easy
"Chloride induced corrosion is a worldwide problem that
results from exposure to a wide range of conditions including marine
environments, application of de-icing salts or contact with salt-laden
air. As the battle rages between salt and the service life of reinforced
concrete structures, the expected service life of new bridges, parking
decks, and marine or coastal structures is extending by tens of years.
These factors make the ability to choose the appropriate corrosion
protection program more critical than ever," said Durning.
he pointed out the following facts:
- The U.S. Federal Highway
Administration has increased the required service life of bridges from
50 to 75 years.
- While the expected service life of parking decks was
once 25 years, it now often exceeds 60 years.
- Many European countries
design highway bridge structures to be safe and in service for well over
Grace introduced the original version of DuraModel in 1997.
Since then, the program has undergone a series of upgrades, the most
recent of which was unveiled at ConExpo-Con/Agg '99 in March. The
current version boasts such features and enhancements as the ability to
address multiple sealer and membrane applications and to determine the
apparent diffusion coefficients from concrete field cores. Service life
results can now be predicted based on local and regional concrete
exposure and permeability.
DuraModel Software has been used in some of
the world's largest and most complex construction projects including
Boston's Central Artery/Tunnel Project, widely known as "The Big Dig."
Grace's Engineering Services Group used the DuraModel Program to help
Big Dig engineers analyze corrosion protection alternatives for several
critical aspects of the project.
already had been specified and put out to bid. Yet, when we sat down and
ran the numbers, the DuraModel Program indicated that the current
specifications for the bridges would not ensure the desired 75-year
life," Durning noted.
