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.

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.
|1/5/22||Best of Decorative Concrete 2021 – Ideas for Including Decorative Concrete in Design||Chris Sullivan (The Fenix Group)||1 Hour||

This presentation will include an overview of the American Society of Concrete Contractors award winning decorative concrete projects across all the major product categories highlighting how concrete can be strong and beautiful. Using the award-winning projects as examples, the presenter will illustrate how various types of concrete materials and finishes can be used across a wide scope of projects. The presenter will explain unique ways in which decorative concrete can be used to enhance projects – providing increased value and aesthetic appeal.
|12/8/21||Workability and the Impact of Workability Retention||Joseph Daczko (Master Builders Solutions)||1 Hour||

Contractors want concrete to be as workable as possible to facilitate placement and consolidation without compromising performance in the hardened state. Concrete producers strive to consistently deliver expected performance attributes. Yet, hydration of Portland cement leads to a change in fresh concrete properties immediately after batching, most notably with respect to mix slump or workability. In air-entrained concrete mixtures, furthermore, modified slump can lead to changes in air content, typically a reduction, and potential rejection of the load. Invariably, rejected loads result in loss of revenue and reduced profits for concrete producers. This presentation will discuss workability retention and the various methods traditionally used to manage it. Additionally, an innovative, new admixture is introduced that provides workability retention without the adverse effects of current practices.
|11/18/21||Ethics - Why Do Good People Do Bad Things?||David Schultz (Hamline University)||2 Hours||
Why do good people and organizations act unethically? Architects and eng…
Why do good people and organizations act unethically? Architects and engineers may confront ethical dilemmas in many forms during their professional practice, especially in the public arena. Many think that only unethical people do bad things, and that ethical people generally do not do bad things. However, the reality is that is often not the case, and this presentation will discuss why good or ethical people often act unethically. In this program, attendees will examine the Minnesota Rules of Professionalism and Ethics and examine examples of ethical dilemmas in professional practice. Specific case studies will be used to provide a foundation for an analysis regarding how the fostering of ethical diversity and thinking about one's personal ethics within organizations can prevent the slippery slopes that lead to administrative evil or unethical behavior.

This webinar will provide a general overview of common horizontal forming systems in use today. We will also discuss some project specific factors that drive the system selection process as well as review examples of building design factors affecting constructability and economy.
|10/13/21||We Have to Build it Where? Solutions for Building on Challenging Construction Sites||Michael Hoeft / Dan Schellhammer / Scott Spisak||1 Hour||
As physical sites grow and expand, means and methods for property develo…
As physical sites grow and expand, means and methods for property development become much more complex. With abbreviated construction schedules and significant liquidated damages, the ability to gain some control of the uncontrollable becomes essential. The earlier this process is recognized and integrated into the project, the better the chance for success. This presentation will address several ways to work with challenging construction sites using cement and concrete; delivering large projects to the owner on time, economically and sustainably.

As computing power become faster and smaller it leads to advances in non-destructive testing (NDT) techniques for structural concrete condition assessment. We will explore some of the newest techniques in the market and discuss how they can be use on structures and construction projects. We will also review a practical approach to finding construction flaws such as honeycomb, void and cracking in new structures as well as scanning to map out corrosion damage in aging structures using many different Non-Destructive Testing techniques.
|7/22/21||Non-Destructive Testing for Assessment of Concrete Structures||Alfred Gardiner, PE (Braun Intertec)||1 Hour||

We live in a constructed world and our lives and livelihoods are inextricably linked to the proper function of our infrastructure and machinery. For this to be safely possible, we must have confidence in the technologies we rely on. Nondestructive testing provides that confidence. To make smart choices, it’s important to have a sound understanding of the purpose, applications, requirements, and different methods of nondestructive testing. This presentation is intended to serve as an overview of various nondestructive testing applications as they are used in the field.
|7/14/21||Concrete Overlays of Existing Asphalt Streets and Parking Lots||Jon Hansen and Phil Kresge (NRMCA)||1 Hour||

The performance life of asphalt surfaced parking lots can be extended by placing a bonded concrete layer on top of the existing asphalt. This technique has been used for many years for highway, street, and parking lot pavements but still engineers and owners are unfamiliar with the process. This session will cover the publication entitled the Guide to Concrete Overlays of Asphalt Parking Lots and demonstrate the steps necessary to properly design and construct a concrete overlay.
|6/17/21||Hot Weather Concrete||Ryan Scott (GCP Applied Technologies)||1 Hour||

Hot weather conditions are not solely related to the air temperature when placing concrete. Those conditions are defined in ACI and ASTM documents. This presentation will focus on being able to define hot weather conditions and its effects on concrete in the plastic and hardened state. This presentation will also provide details on how to overcome the conditions of hot weather when placing concrete.
|6/8/21||The Top 10 Ways to Reduce Concrete’s Carbon Footprint||Donn C. Thompson AIA, LEED AP BD+C (National Ready Mixed Concrete Association)||1 Hour||

Concrete is unique among building materials. Its formulation is highly influenced by its application. Design professionals and contractors have a greater influence on concrete formulation than they do with other building products. Concrete can be made stronger, lighter, more flowable, stiffer, less permeable, and even weaker depending on performance needs. No other building material is that versatile. This presentation will discuss how design and construction teams can implement ten simple strategies to reduce concrete’s carbon footprint today. The recommendations are listed broadly in order of priority, but not in order of impact reduction. All are important and should be implemented. In addition, the strategies are meant to achieve a lower carbon footprint without impacting other desired performance capabilities for the concrete.
