This presentation will discuss materials being developed for the concrete industry that will lower the embodied carbon of a yard of concrete.  Some materials are ready to use and do not require additional support or alteration of how we produce, place, and finish concrete.  Others will require new approaches, new specification, and new understanding of chemistry. 

No credits will be awarded for viewing recordings of the webinar. 

The webinar is being sponsored by the Iowa Ready Mixed Concrete Association, the Minnesota Concrete Council, the North Dakota Concrete Council, the Oklahoma Ready Mixed Concrete Association, the South Dakota Ready Mix Association, and the Wisconsin Ready Mixed Concrete Association.

Mass concrete (or thermally controlled concrete) typically requires implementing thermal control measures to reduce maximum temperature and mitigate temperature difference. Specified temperature limits and thermal control requirements can affect mix design proportions, materials selection, reinforcement details, construction operations and compliance to specifications for the work. Many specifications still limit concrete temperatures to overly conservative default values without recognizing concrete properties and performance that allow alternative temperature limits more suitable for the specified work while maintaining quality and improving constructability. This issue frequently results in challenging scenarios that create design difficulties and unnecessary constructability problems for mass concrete. This presentation focuses on the implementation of today’s knowledge of mass concrete and best practices to overcome mass concrete challenges and facilitate solutions in projects. A special emphasis will be given to the technical updates provided for mass concrete requirements and guidance progressing in North America industry standards.

This webinar will outline the benefits of using Insulated Concrete Forms (ICFs) in construction, especially in regard to Rural and Tribal projects.  ICFs are a key component in DSGW’s strategy to design Net Zero projects.  This presentation will show examples of ICF and Net Zero design, in particular the Fort Totten Alternative CTE School, the country’s first Net Zero school on Tribal lands in North America.  

The 12,500 square foot, $3.8 million net zero Fort Totten Alternative CTE School was designed to produce more energy than it consumes while ensuring to meet other standards common when designing a net zero facility. There are other net zero schools in the United States, but this new school is the first to be built on tribal land and the first in North Dakota.

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.

Many design engineers, contractors and project owners appreciate and fully recognize the significant value of concrete parking lots.  However, there are some that still need some convincing.  This presentation covers concrete parking lot features and benefits and gives suggestions for addressing common concrete paving misconceptions.

With the increased focus on sustainability initiatives in construction, prescriptive requirements in specifications often restrict the concrete producer’s ability to optimize concrete for sustainability without compromising functional performance for project needs. The presentation will discuss these impacts and outline the development of a guide performance specification by ACI Committee 329.

Part of the Sustainable Structures Webinar Series: This one-hour program is intended for professional designers and engineers. The attributes of precast concrete will be presented, demonstrating how these qualities may be applied to the design and construction of safe and efficient storm shelter facilities. The versatility and resiliency of precast concrete will be further highlighted by a video demonstration, and a series of case studies.

Part of the Sustainable Structures Webinar Series: Prescriptive building code requirements represent provisions for the least safe structure that may legally be built in a jurisdiction. Over the past 20 years, the building design and construction industry have witnessed an increase in the number of trade-offs of passive fire safety features for active systems. As natural disasters attributed to climate change continue to escalate, the population of neighborhoods located along with the wildland-urban interface increases, and fire and emergency access to buildings in densely populated areas is obstructed, multiple drivers arise to consider more robust construction for our built environment.

The presentation will provide an overview of increased risks from natural and human hazards, identify approaches to mitigate their effects through voluntary and mandatory strategies and demonstrate the importance of incorporating standards for resiliency beyond minimum code requirements.

This presentation will introduce the work of NEU, an ACI Center of Excellence for Carbon Neutral Concrete, and discuss the important role of concrete in reaching carbon neutrality. The presentation will provide an overview of key terms and concepts, the latest information on green concrete codes, and examples of low carbon practices for the concrete industry for the present and future.
