Concrete is the world’s most widely used construction material. Yet, the production of portland cement, an essential constituent of concrete, leads to greenhouse gas emissions into the atmosphere. The production of 1 ton of portland cement clinker releases approximately one ton of CO2 and other greenhouse gases. Environmental considerations have been a major thrust for the sustainable development of the cement and concrete industries. A sustainable concrete structure is designed and built to have a positive environmental footprint during its entire life cycle. Concrete is increasingly being considered as a sustainable material owing to its low inherent energy requirements and little associated waste. Not only is it made from some of the most plentiful resources on Earth, it can also be made with numerous recycled materials and by products and is itself entirely recyclable. Emerging breakthroughs in concrete technology have allowed the production of ultra high performance concrete requiring fewer raw materials, along with structures that are much more durable to reduce maintenance, repair, and reconstruction.
Learning Objectives:
(1) Demonstrate how to evaluate concrete mixtures with various waste-by-product and recycled materials;
(2) Recognize many different types of testing that could be performed on new concrete mixtures produced with recycled materials;
(3) Explain the various methods to design and validate the concrete produced by new recycled materials;
(4) Specify emerging technologies in the concrete produced by recycled materials and its application in civil infrastructures.

10:00 AM - 12:00 PM

Moderators: Yail Jimmy Kim, Chris P Pantelides

Durability is one of the most important requirements for sustainable infrastructure. Federal, state, and local agencies expend significant effort to maintain the quality and condition of aging civil structures, especially those in aggressive service environments. Among many factors, durability influences the service life and integrity of concrete materials and structures. Extensive research has been conducted to understand the deterioration mechanisms of concrete in an effort to extend the longevity of concrete members. In this session, presentations of both experimental and analytical investigations are of interest, which may include the durability of concrete structures reinforced with steel or fiber-reinforced polymer bars, modeling of service life for concrete under aggressive environments, and the structural integrity and resilience of rehabilitated members. The session emphasizes recent research findings and provides an opportunity to discuss present challenges and technical issues. Critical information is given to those who lead tomorrow’s structural design and construction with an emphasis on durability, service life, and integrity, including practicing engineers, government officials, and academics.
Learning Objectives:
(1) Define the state of the art of structural performance subjected to environmental and mechanical distress;
(2) Identify research needs to advance the knowledge associated with the durability, service life, and integrity of concrete bridges and buildings;
(3) List efforts to establish a new trend in the design and construction of concrete bridges and structures;
(4) Link laboratory investigations with practical site application.

10:00 AM - 12:00 PM

Moderators: Shahria Alam, AHM Muntasir Billah

Major seismic events around the world along with the aging and deterioration of infrastructures keep increasing the need for repair/strengthening and rehabilitation of existing bridges. Seismic repairing and strengthening are an area that has seen major developments due to the availability of robust numerical simulation frameworks, large experimental facilities, structural health monitoring techniques, development of advanced materials and construction techniques, and sophisticated performance-based seismic design and assessment methodologies. Despite the progress, there are many challenges yet to be addressed. With the increase in transportation demand and more stringent seismic performance requirements, bridge retrofit, and repair is an important task for engineers and researchers. Bridge retrofits usually involve functional upgrades (such as deck widening) and seismic upgrades (such as strengthening seismic load path). The effects of the two upgrades are usually coupled and need to be analyzed. Therefore, more sophisticated analysis and customized solution is needed. While providing structural upgrade solutions to seismic issues, engineers also need to reduce the interruption to the traffic as much as possible.
Learning Objectives:
(1) Highlight ongoing research studies on the performance of repaired/retrofitted bridges under extreme events
2. Present recent findings regarding the behavior of retrofitted concrete bridges under axial and combined flexure/lateral loads or environmental loads (corrosion, freeze-thaw cycles, high-temperature differential, freeze-thaw cycles, and ice load impact)
3. Discuss the new experimental and numerical approaches for the rehabilitation of concrete bridges with seismic isolation.

Graphene and its derivatives present a relatively new family of nanomaterials featuring unique quasi-2D layered structure. The thickness of single-layered graphene nanosheets is approximately 1 nm, while the median size of the lateral dimension is about 4 µm depending on the specific preparation method. Similar to carbon nanotubes and carbon nanofibers, graphene can be employed to endow cementitious materials with smart functionalities (e.g., by monitoring their stress-strain behavior). Recent laboratory studies have increasingly demonstrated that the oxygen-containing functional groups on the surfaces of graphene oxide (GO) and reduced GO make them a new type of multifunctional admixtures for cementitious materials. This session will bring to light to new frontiers and recent research findings and provide an opportunity to discuss the present challenges and technical issues. The session aims to engage a diverse group of distinguished speakers and serve to inspire researchers and practitioners who are interested in the use of graphene-based admixtures in paste, grout, mortar, and concrete.
Learning Objectives:
(1) Define the state of the art of using graphene-based admixtures (including carbon nanotubes) in concrete;
(2) Identify research needs to advance the knowledge associated with the appropriate use of graphene-based admixtures in concrete;
(3) Describe recent advances that explore sensing capability of cementitious mateirals incorporating graphene-based admixtures;
(4) Identify possibilities of using graphene-based materials for interfacial engineering of cement or cementitious materials.
