7:00 AM - 8:30 AM

Moderator: Ben Dymond

Speaker: Lawrence Novak, Portland Cement Association
Topic: Top Ten Useful Lessons for Structural Engineers
Samuel Smiles, a Scottish author (1812-1904), wrote that “We learn wisdom from failure much more than from success. We often discover what will do, by finding out what will not do; and
probably he who never made a mistake, never made a discovery.” Typically, much is written and presented about outstanding projects in our profession. Rarely do we talk about the philosophy behind the design... even rarer do we take two steps back and delve into the important life lessons which can be gleaned from a career in our profession and the importance of building resilient communities. We would like to take this opportunity to lead the
group on an amazing journey of discovery to explore what we really do and what the world expects of us. The thoughts offered are geared toward individuals at all phases of their far-reaching careers—from students to those enjoying their retirement—and all the wonderful experiences and challenging decisions we encounter along the path.

There seems to be an expectation that casting members with SCC automatically produces surfaces free of defects. This session will present case studies, factors affecting surface defects when SCC is used, and methods to improve surface appearance to minimize repairs/rework to bring surface finish in compliance with Contract Documents.
Learning Objectives:
(1) Identify how different factors, including placement rates, drop heights, level of reinforcement, flowing distances, viscosity, slump flow levels, form material and use of form release agent, can affect surface appearances when using SCC;
(2) Discuss common defects such as surface voids, placement lines, honeycombs, and others, and how to minimize their occurrence when using SCC;
(3) Explain how special care in the selection of the formwork materials, mix design, and placement methods can lead to blemish free-walls for surfaces designated as architectural concrete.
(4) Summarize methods for evaluation of surface finish, including a proposed image analysis methodology on formed surfaces of concrete cast with Z-shaped elements.

Energy Code requirements are revised and implemented at regular intervals, requiring the concrete industry to not only stay abreast of new Code requirements and compliance procedures, but also to develop new technologies to improve the energy performance of concrete buildings. This session presents three papers addressing both code compliance and new technologies. ASHRAE 90.1-2016, “Energy Standard for Buildings Except Low-Rise Residential Buildings,” has increased verification and documentation requirements for minimizing air leakage through buildings. Essentially, two compliance paths exist. In the first, whole buildings can comply by meeting testing requirements. In the second, individual components can pass by meeting certain testing requirements or being constructed of concrete or other materials that limit air leakage. However, using the second method, the building must have: (1) a design review, and (2) periodic inspection of the air barrier components during construction while they are still accessible for inspection and repair to verify compliance. Using either compliance path, documentation and reporting is required. The code requirements, their implications for concrete buildings, and compliance paths available will be discussed in detail. Phase-change materials (PCMs) have been widely proposed to enhance building energy efficiency as they can regulate the indoor temperature when used in building envelopes. To be incorporated in concrete or masonry, PCMs have to be encapsulated or stabilized in lightweight porous inclusions.
Learning Objectives:
(1) Explain the Air Leakage Requirements in ASHRAE 90.1 and IECC;
(2) Review strategies for documenting compliance with the requirements;
(3) Describe methods of incorporating phase change materials in concrete without leaching;
(4) Demonstrate the merits of phase change materials in enhancing the energy efficiency of concrete.

According to the American Coal Ash Association, the production of fly ash has declined with the closure of several coal power plants due to environmental regulation and competition from other fuel sources. Over the same period, the utilization of fly ash has steadily increased. With advances in renewable energy technologies and the concrete industries pushing for higher fly ash usage, these trends are expected to continue. Even today, concrete end users are being required to seek alternative sources of fly ash because of shortages. Researchers have already begun looking for viable fly ash replacements. This forum will provide insight to ongoing activities of alternatives to fly ash.
The forum will focus on the following themes:
- How can positive aspects of fly ash such as reduced heat of hydration, increased durability, etc. be provided through other means?
- Can other current supplementary cementitious materials provide similar performance and economics?
- What other materials should be considered when seeking a fly ash replacement?
- Should non-portland cement binders be prioritized over alternative pozzolans?
A panel of experts from various backgrounds will discuss these questions and more to provide the audience information regarding the latest developments of concrete research. The forum will start with short presentation by each of the panelists. The presentations will be followed by an interactive discussion with the audience.
Learning Objectives:
(1) Summarize the benefits of fly ash on performance of concrete mixtures;
(2) Discuss the availability and potential future fly ash sources for the concrete industry;
(3) Identify alternative materials that have the potential to be used in concrete in lieu of fly ash;
(4) Describe the benefits as well as the challenges limiting the implementation of fly ash replacement materials in practice.
