Sustainable Structural Concrete for Accelerated Construction

Contemporary construction projects are leaning towards resilient structural solutions with emphasis on sustainable and durable materials. This approach is of great significance for a multitude of applications such as retaining walls, bridge decks, and concrete pavements. Conventional construction practices are associated with several difficulties and drawbacks, such as prolonged site preparation procedures, mitigated work zone safety due to exposure of workers to active traffic, traffic congestion, and environmental costs. As a result, the need for shorter construction periods motivates the development of alternative solutions such as accelerated bridge construction (ABC) techniques. The accelerated construction method incor­porates precast concrete products such as Ultra High Performance Concrete (UHPC) joints, High Performance Concrete bridge decks and fast-setting concrete grouts that combine strength and dura­bility in concrete. From a structural point of view, understanding the effect of materials constituents on the mechanical properties of UHPC and HPC is essential to guar­antee the best working conditions. In addition, sustainable concrete solutions are also focused on reducing the CO2 emission in the cement production and concrete industries, as each ton of cement produced accounts for 0.92 tons of CO2 emissions. This also motivates the need to inspect the standardized ASTM C150 requirements of 10% limestone and inorganic processing additions (IPA) to cement. Limestone and IPA mix design optimization aims to mitigate environmental problems by reducing the amount of raw materials burned to produce cement and to reduce the carbon footprint up to 10% of total CO2 emissions.

Dr. Mohsen A. Issa received his BSCE, MSCE and Ph.D. degrees from the University of Texas at Arlington, USA and postdoctoral from the University of South Florida, Tampa, USA. Professor Issa served as the Director of Graduate Studies for the Department of Civil and Materials Engineering for 8 years. He is the Director of the Structural and Concrete Research Laboratory at UIC. Professor Issa has been teaching various courses in the field of reinforced and prestressed concrete structures, steel design, bridge design, and concrete materials.
Through his research funding, Dr. Issa has graduated 22 Ph.D., 15 Masters graduate students and currently supervising 7 PhD students. Professor Issa has been honored with several teaching and research awards. He is a Fellow of the American Concrete Institute (ACI) and American Society of Civil Engineers (ASCE).
He is a registered Structural Engineer in the State of Illinois as well as Professional Engineer in the State of Florida. He has published over 150 papers in reputed refereed journals and proceedings. Dr. Issa has also moderated and organized a large number of technical sessions within the civil engineering infrastructure and made numerous invited keynote lectures and presentations nationally and internationally. Dr. Issa has been the principal investigator for research projects funded by National Science Foundation, Illinois Department of Transportation, Chicago Department of Transportation, Illinois Transportation Research Center, Illinois Center for Transportation, Federal Highway Administration, U.S. Army Construction Engineers Research Laboratories, and other local industries.
