SIMCO Presents at the NACE Concrete Service-Life Extension Conference

SIMCO Technologies, in collaboration with Rutgers University, Center for Advanced Infrastructure and Transportation, will be presenting at the NACE Concrete Service-Life Extension Conference taking place in Orlando Florida, from May 23^rd to 25^th. The technical conference “Calculation of Credits to Optimize Lifetime Maintenance Interventions on Concrete Transportation Structures” is scheduled on May 24^th.

With over 50% of concrete repairs that fail within the first 10 years or less, this year’s conference is focused on the durability of concrete structures.

Engineers, designers, scientists, contractors, and inspectors from around the world will be attending various technical presentations on:

• Concrete Condition and Mechanisms of Deterioration
• Diagnostics of Concrete Failures
• Service Life and Durability
• Concrete Repair and Corrosion Mitigation

SIMCO’s technical presentation is aimed at demonstrating how it is possible to develop an optimized strategic maintenance program for concrete structures by calculating the impact of preventive maintenance interventions on individual structural elements. This maintenance impact is based on the condition of the elements and their expected degradation mechanisms. The optimization is based on technical knowledge from field intervention specialists, testing and characterization of repair and in-place materials, implementation of state-of-the-art maintenance strategies, and degradation modeling of pre- and post-maintenance materials. The calculation of a value-called maintenance credit can be used to assign credits related to the remaining service life of the structural elements based on their specific degradation state.

The presentation will also demonstrate the use of maintenance credits in: (1) planning repairs, and (2) selecting the most appropriate intervention among several maintenance scenarios, which include the selection of materials and time of intervention. In addition, the presentation will also provide the benefits of planning and modeling maintenance for specific structures based on their degradation state instead of element age (e.g., by using the Markov Chain approach). An example illustrating the optimization of the maintenance of bridge decks by selecting different maintenance scenarios will also be provided.

Join us on May 24^th at 10 am
Rosen Plaza, Orlando Florida
