8:30 AM - 10:30 AM

Moderator: H Celik Ozyildirim

Mechanical properties and cracking resistance are important in concrete structural design, and they affect the long-term performance of structural component. For example, additional strain caused by shrinkage would increase stress; however, higher creep may lead to relaxation and can reduce stress. Higher deformations can lead to higher stresses that could influence deflection, camber, and prestress loss in prestressed concrete elements and affect cracking potential in cast-in-place applications. Comparing with conventional vibrated concrete (CVC), self-consolidating concrete (SCC) generally requires increased amounts of cementitious and fine materials, or a larger volume of paste, and increased dosages of admixtures to achieve high workability and stability. SCC also has smaller maximum size of aggregate and reduced amount of coarse aggregate. These features could affect the strength, shrinkage, and creep behavior of SCC. This session will summarize recent work on the creep and shrinkage behavior of SCC as well as their effects on the mechanical properties and performance in precast and cast-in-place applications.
Learning Objectives:
(1) Explain shrinkage and creep of cast-in-place and precast SCC;
(2) Discuss shrinkage and creep prediction models for SCC including supplementary cementitious materials;
(3) Describe creep behavior of SCC reinforced with hybrid fibers;
(4) Report the time-dependent performance of an in-service SCC girder bridge.

Title: The Big Picture for Reducing Concrete Carbon Footprints: A Practical Conversation
Over the last decade, and especially the last two years, there has been a tremendous amount of research, communication, and focus on reducing the carbon footprint of concrete construction, and how concrete helps to reduce the volume of greenhouse gasses. If we look at discrete elements within the life cycle of concrete, there are gains to be achieved, and these claims and research prove to be true. However, to see those gains, and continue them, we have to have a much bigger perspective about the choices we make when constructing out of concrete. This means we have to take a more holistic view of how we make those choices, and what technical sacrifices we are willing to make, to see those ultimate results. This presentation will feature several case examples as well as a practical roadmap as to how those discrrete choices can impact the overall goals for achieving a reduction in carbon footprint when concrete is the primary building material.
