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.

View Description

---Close---

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.

View Description

---Close---

More than 75% of all concrete is made with fly ash. In some states, fly ash is specified for all concrete structures. Several regional shortages in the past few years coupled with increasing EPA regulations and plant conversions from coal to natural gas has put the future of fly ash in question. This presentation will go over where the fly ash industry is today, what is being done to help with supply, and what is being done to help ensure a strong fly ash market for the future.

View Description

---Close---

Part of the Sustainable Structures Webinar Series: Now that architects have a good understanding of environmental impacts related to energy use, the next design frontier in tackling climate change is reducing the embodied carbon in buildings. This live webinar will focus on best practices for determining the embodied carbon in a building, including credible sources for embodied carbon data. It will introduce common practices and misconceptions about comparisons of embodied carbon. A case study will be presented that highlights how design decisions may be influenced when comparing among up-front carbon, use-phase carbon, or whole-life carbon. The presentation will highlight existing tools related to quantifying embodied carbon.

View Description

---Close---

WJE carried out independent studies related to the 2018 collapse of the FIU Pedestrian Bridge in Miami. Most significantly, WJE developed and tested full-sized specimens to evaluate the significance of the National Transportation Safety Board’s (NTSB’s) finding that the construction joint between the northernmost diagonal and deck was left in an as-placed condition, rather than intentionally roughened as required by the project specifications. The webinar also describes WJE’s independent review of shear friction strength in accordance with the AASHTO Code.

 

The presentation describes the details of the experimental program that demonstrated that, had the construction joint been roughened as required by the project specifications, the collapse would not have occurred. Contrary to NTSB’s findings, the contractor’s failure to roughen the surface was the primary cause of the collapse.

Concrete is the foundation for everything we build. Concrete is an integral part of homes, businesses, schools, offices, churches, roads, and bridges. The concrete industry is in need of people who aren't afraid of hard work. A career in the concrete industry not only pays well but gives individuals the chance to build something that will stand the test of time. Right now, there is a growing need for concrete contractors, equipment operators, ready mix concrete truck drivers and quality control personnel. #ConcreteTough is a Nebraska based workforce recruitment campaign that exposes youth to the concrete construction industry. This message is communicated through participating in various career fairs, concrete 101 programs, and presented to numerous schools on the different careers the concrete Industry offers. Attendees will learn ways that they can incorporate concrete career awareness into their own workforce recruitment efforts.

A short overview of the new Concrete Industry Management degree at South Dakota State University will also be included with this webinar.

View Description

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.

Lighter, faster and more cost effective than other forms of construction, Insulating Concrete Forms (ICFs) are quickly becoming the construction method of choice for all forms of construction including single and multi-family, hotels, schools, offices. Concrete contractors, masons and framers have an opportunity to learn how their trade can work with ICFs to enhance their competitiveness in today’s construction environment. The presentation will focus on how to communicate basic ICF detailing, design efficiencies, and other necessary information to designers who may not be familiar with ICF construction. Also included in the presentation will be information on how ICF’s can affect other sections of the specification, best construction practices, and tips on how to determine labor costs for an ICF project.

The drive for sustainability often creates a tension between durability, constructability an owner’s expectations. The presentation will concentrate on changes in owners expectations such as low maintenance, crack free and aesthetically pleasing slabs on grade. These will be reviewed in the context of new materials, such as alternative sources of binder, Type IL cements, sinusoidal or plate dowels, and the various techniques used to increase the spacing between joints, or even to remove them completely.

Concrete provides structures with strength, rigidity, and resilience from deformation. These characteristics, however, result in concrete structures lacking the flexibility to move in response to environmental or volume changes. Cracking is usually the first sign of distress in concrete. Cracking of concrete flatwork is natural, expected, and accepted. However, cracks may affect appearance, performance, and maintenance costs.  This presentation will discuss the various types of concrete cracks and how to best minimize their occurrence.

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.
