    Portland Limestone-Cement and New Industry Initiatives

    Date: January 26, 2022

    Time: Noon – 1:00 pm CST

    Presenter: Jamie Farny (Director, Environmental Measurement and Metrics at the Portland Cement Association)

    Credits: 1 PDH and/or 1 AIA CES LU (AIA Course #MCC012622)

    Registration Link: https://cvent.me/a8zakZ 

    Description: With a growing interest in sustainability, the construction industry is looking for solutions to help reduce its carbon footprint. The Portland Cement Association’s newly released Roadmap to Carbon Neutrality lays out the cement and concrete industry’s commitment to a lower carbon future. With its proven performance, portland-limestone cement, or PLC, is ready to play a key role, yet many designers and specifiers don’t know about it. This program will explain what PLCs are, how to use them, and their effects on fresh and hardened concrete properties. Several examples of PLC projects in the U.S. over the past decade will show how others have used it successfully.

    Learning Objectives:

    • 1.    Understand the potential savings in CO2 footprint when using PLC to make concrete and explain how that is achieved.
    • 2.    State the replacement level and how to modify mix designs when swapping in PLC for OPC.
    • 3.    State how supplementary cementitious materials (SCMs) contents are affected by using PLC.
    • 4.    Describe how PLC affects fresh and hardened concrete properties relative to OPC concrete.

    Speaker Bio: Jamie Farny promotes the use of cement-based materials for various applications by focusing on sustainability, resilience, energy efficiency, durability, and other key benefits. He assisted with development of PCA’s new campaign to raise awareness of portland-limestone cements (PLCs) for improved sustainability of concrete construction. He holds a B.S. degree in Civil Engineering from the Illinois Institute of Technology.

    Description:  Concrete is used in nearly every structure we build today, including buildings, bridges, homes and infrastructure. With greater emphasis placed on sustainability, design professionals are faced with the challenge of meeting traditional design criteria with evolving criteria that support green building and efforts to reduce impact on climate change. Performance-based specifications for concrete represent an important synergy with sustainability initiatives because they provide the opportunity to optimize mixtures for performance that can also reduce environmental impacts. Prescriptive specifications often adversely impact the environmental footprint of concrete structures. This presentation outlines how concrete performance can be improved while lowering environmental footprint by implementing performance-based specifications.

    Learning Objectives:

    • 1.    Understand the difference between performance-based specification and prescriptive specifications.
    • 2.    Discover how performance-based specifications can improve performance and lower environmental impact of concrete structures.
    • 3.    Learn how to implement performance-based specifications in projects.
    • 4.    Demonstrate the importance of balancing structural and architectural performance of concrete with green building strategies.

    Speaker Bio: Donn C. Thompson is the Senior Director, Building Innovation for the National Ready Mixed Concrete Association.  Based in Kenosha, WI, he supports the Build with Strength program, demonstrating the first cost and long-term advantages of ready mixed concrete building systems throughout eight Midwest states.   A licensed architect and LEED accredited, Donn has over 20 years of practical experience in design and construction.  More recently he has worked for over 23 years in the cement and concrete industry holding a variety of technical promotion and sales positions.

    Green Concrete – Where We Are Now and How Green Can We Get?

    Date: April 27, 2022

    Time: Noon – 1:00 pm CST

    Presenter: Kevin MacDonald, PhD, P.E. (President, Beton Consulting Engineers)

    Credits: 1 PDH 

    Registration Link:  https://cvent.me/8ZMV7E

    Description: Green building is the concept of constructing buildings we need today without depleting resources for future generations. In the new world of sustainable building, information about the strength, durability, and indestructible nature of concrete as a resourceful building material is emerging. Amid the teardown-and-replace mentality still pervasive in the world today, concrete stands out defiantly. Try to replace concrete with an alternative building material, and you'll be hard pressed to find a substitute possessing the same thermal qualities, design flexibility, and permanence. This presentation will discuss where we are at as a green industry and the various ‘green” efforts that have been used in concrete production, such as substituting relatively high percentage of cement by fly ash (up to 100%), the use of other natural pozzolans, and development of concrete with recycled or waste materials. The presenter will also discuss where the industry might be headed in the future. Finally, problems in the realization of and potential barriers to green concrete construction are also discussed.

    Learning Objectives:

    • 1.    Understand the basics of SCM replacement in concrete mixtures.
    • 2.    At the conclusion of the presentation, participants will have a better understanding of what is being done to make concrete construction more environmentally friendly.
    • 3.    Learn where the concrete construction industry might be headed with regards to green building and sustainability.
    • 4.    Understand the problems in the realization of and potential barriers to green concrete construction.
