St. Louis — Net Zero, LLC broke ground in January on three display homes for its Saint Louis Park Place residential community within the NorthSide Regeneration development in North St. Louis City. Net Zero purchased lots from NorthSide Regeneration to build 250 energy-efficient, single-family homes adjacent to the site of the future multibillion-dollar National Geospatial-Intelligence Agency (NGA) Western Headquarters.

The display homes, under construction at the intersection of Montgomery and 20th streets, are expected to be completed in April, according to Net Zero owner Dwight Arant and his builder Jon Bish, with construction of sold homes set to begin this spring.  Arant, a former Marine and retired businessman who was born and spent his early childhood in North St. Louis City, said he is looking forward to bringing more residents back to the community that his family once called home.

“We are excited to be working with NorthSide Regeneration to bring this residential community project to North St. Louis City,” said Arant. “Saint Louis Park Place will provide much-needed housing for the existing community and future employees of NGA and St. Louis as a whole. While setting the standard for energy efficiency in new homes, the homes are designed to align with the historical characteristics of the area.”

The new homes are designed by St. Louis-based architect Klitzing Welsch Associates. Prices for the homes will be set after the display homes are completed, and are expected to range in size from 1,200 to more than 3,000 sq. ft. One, two- and three-story models will be available with a range of options.  All the homes will have the potential to be “Net Zero,” which means the homes will produce enough renewable energy (from solar PV) to power themselves. This means that utility bills to heat, cool and power the homes will be very low, or eliminated.

NorthSide Regeneration (NSR) is a mixed-use community development – a self-sustaining neighborhood of people, cultures, economic opportunity, safety and education with the infrastructure and growth to support key, necessary services for the community. The original development encompasses over 1,500 acres and borders downtown St. Louis. Jobs have always been the primary motivator for NSR with a goal of more than 43,000 construction jobs and 22,000 permanent jobs generated by the development’s activity.

A new way of protecting concrete from fire damage using materials recycled from old tires has been successfully tested by researchers at the University of Sheffield. The team used fibers extracted from the textile reinforcement commonly embedded into tires to guarantee their performance. Adding these fibers to the concrete mix was shown to reduce the concrete’s tendency to spall – where surface layers of concrete break off – explosively under the intense heat from a fire.

Using manmade polypropylene (PP) fibers to protect concrete structures from damage or collapse if a fire breaks out is a relatively well-known technique. Many modern structures, including large scale engineering projects such as Crossrail, have used concrete that includes PP fibers for protection against fire spalling.

The Sheffield study is the first to show that these fibers do not have to be made from raw materials, but can instead be reclaimed from used tires. The results are published in the journal Fire Technology.

“We’ve shown that these recycled fibers do an equivalent job to ‘virgin’ PP fibers which require lots of energy and resources to produce,” explains lead author Dr Shan-Shan Huang, in the Department of Civil and Structural Engineering at the University of Sheffield. “Using waste materials in this way is less expensive, and better for the planet.”

The fibers melt under the intense heat from a fire, leaving networks of tiny channels. This means that moisture trapped within the concrete is able to escape, rather than becoming trapped, which causes the concrete to break out explosively.

“Because the fibers are so small, they don’t affect the strength or the stiffness of the concrete,” says Dr Huang. “Their only job is to melt when heat becomes intense. Concrete is a brittle material, so will break out relatively easily without having these fibers help reducing the pressure within the concrete.”

Protecting the concrete from fire spalling means that steel reinforcements running through the concrete are also protected. When the steel reinforcements are exposed to extreme heat they weaken very quickly, meaning a structure is much more likely to collapse. The Liverpool Waterfront Car Park suffered this kind of damage during a fire in 2017, leading to the entire structure eventually having to be demolished.

Collaborating with Twincon, a Sheffield-based company that develops innovative solutions for the construction industry, the researchers have also developed technologies for reclaiming the fibers from the used tires. This involved separating the fibers from the tire rubber, untangling the fibers into strands, and then distributing them evenly into the concrete mixture.

The team plan to continue testing the material with different ratios of the fibers to concrete, and also using different types of concrete. They also plan to find out more about how the materials react to heat at the microstructure level. By scanning the concrete as it is heated, they will be able to see more precisely the structural changes taking place inside the material.

Conshohocken, Pa. — ASTM International will sponsor Kaitlyn Bishay, a senior civil engineering major at the University of Alabama, for the prestigious Washington Internships for Students of Engineering (WISE) program. This announcement coincided with “Girl Day” of Engineers Week, which encourages girls and young women to consider careers in engineering.

WISE is a competitive summer program in Washington, D.C., offered annually to about a dozen engineering juniors and seniors interested in public policy. The program provides housing and a stipend.

Bishay is pursuing a degree in civil engineering with a minor in educational studies. She is particularly interested in civil and environmental engineering policy, specifically related to water. Bishay’s activities include leadership programs like “Beat Auburn Beat Hunger,” an annual food drive designed to end food insecurity in Alabama, and clubs such as the University of Alabama Asian-American Student Association and Crimson Clay.

After an internship with John Labib & Associates, Structural Engineers in Los Angeles, Bishay’s interest in policy developed, stemming from what she calls “a belief in a greener tomorrow,” and “the intersection of public policy and the public good.”

DiscoverE’s Engineers Week (http://discovere.org) recognizes the many contributions engineers make to society. The WISE internship is one of many scholarships and grant programs ASTM International provides to student members. Students can join free (www.astm.org/studentmember). For more about the WISE program visit www.wise-intern.org.

The title of the MIT Concrete Sustainability Hub’s (CS Hub’s) next webinar poses both a challenge and a question. “Fix My Road: What can YOU do (with your smartphone) to make OUR Infrastructure Great Again while addressing Climate Change?” will propose a new, crowdsourced way to assess the state of infrastructure.

Using acceleration data from a smartphone mounted inside of a vehicle, MIT researchers say they have developed a method to assess road roughness properties. This method can also be used to map the aggregated excess fuel consumption, associated environmental footprint, and “health” impact due to these road conditions, they say.

The one-hour webinar is offered at no cost and is scheduled for 11 a.m. (EST) on February 28. Registration is required for all participants. The webinar will be presented by Dr. Franz-Josef Ulm, MIT Professor, and Faculty Director of the Concrete Sustainability Hub.  The webinar was developed collaboratively by the researchers at the CS Hub and several other universities.
