View Description

---Close---

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.

1/13/21 Better Design Through Embodied Carbon - Part One of the Sustainable Structures Webinar Series Emily Lorenz, PE 1 Hour

Part of the Sustainable Structures Webinar Series
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---

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.

View Description

---Close---

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.

Concrete is the second most used material in the world, only exceeded by water. It is also one of our oldest construction materials starting thousands of years ago. It continues to evolve and allows us to make the tallest buildings, bridges, and roadways.

So how did our ancestors find out that if we heated rocks, we could make cement and then make concrete? How did we discover the multi-step process of making our modern concrete?

This presentation will take us through the journey of how cement and concrete developed. Along this journey, we will see how the discovery of fire, bricks, pottery, pyramids, and lighthouses played a major role in the development of concrete.

View Description

---Close---

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.

View Description

---Close---

Many issues related to construction can be alleviated by a fundamental understanding of the basics of concrete. This starts with knowledge of the standard components of a concrete mixture including cementitious materials, aggregates, water, and admixtures and their importance on the properties of fresh and hardened concrete. The combination of these materials in various proportions can produce mixtures suitable for a wide range of applications and placement methods. Once placed, the concrete must be properly cured to develop its intended properties. This presentation introduces the basics of concrete and describes its importance and application as a construction material.

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.

View Description

---Close---

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.

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.
