MCC SCHOLARSHIP PROGRAM

This presentation is part of the Sustainable Structures Webinar Series.  The Sustainable Structures Webinar Series was developed cooperatively by cast-in-place and precast concrete associations from the Midwest region of the United States including Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, South Dakota and Wisconsin.  The goal of the cooperative effort is to bring a greater awareness of the sustainable and resilient nature of concrete building systems to the design, construction, and development communities via quality continuing education programs.

This presentation will give a brief basic overview of insulating concrete forms (ICFs) and precast concrete.  The presenters will answer the following questions:  What are ICFs and what is precast concrete? What are the benefits of each system?  How is each installed/erected?  What types of buildings are constructed from precast concrete and ICFs?    

Presenters: Micah Garrett (Chair of the ICFMA Education Committee, and COO of BuildBlock Building Systems) and Randy Wilson (Director, Architectural Precast Systems at PCI)

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.

The concrete pumping equipment available today is more advanced, reliable, and prolific than ever before. So why can’t I find one that can move this perfect mix I just created?

The factors that can affect concrete pumping are numerous, inter-related, and sometimes hidden, making the predicting of pumpability seem elusive. So how is the construction industry, which is becoming ever more cost conscious and filled with complicated and demanding concrete requirements, to deal with it on a more simplified level?

This presentation will discuss some of the over 50 factors that affect concrete pumping, the basics of how concrete pumping works, how mix designs can be adjusted to accommodate the application’s multiple requirements, and what can be done to help eliminate the jobsite problems that result in a finger pointing exercise and costly downtime.

The presenter will be Jim Bury, Director of Placing Equipment at Conforms.

This presentation will discuss changes in the volume of air entrained concrete in pumped concrete. The work shows that during pumping the air volume will decrease and if measured immediately after pumping will be lower than what is found in the final concrete. These findings are supported by hardened air void analysis, freeze thaw tests, and measurement of the air void volume and spacing over time in the fresh concrete with the Super Air Meter. The presentation makes recommendations for modifications to the current testing specifications based on the findings.

The presenter will be Tyler Ley Ph.D., P.E. - Professor at Oklahoma State University
