Secret ingredient for high-strength bridges

Last fall, a new bridge was built east of Jefferson City, Mo., that incorporates an unusual, high-strength concrete mix in its girders and support structure. The three-span bridge is outfitted with sensors and other instrumentation to collect data on how well the bridge performs over time.

It’s another milestone for John J. Myers, professor of civil, architectural and environmental engineering, who worked on the project with the Missouri Department of Transportation and Missouri S&T’s National University Transportation Center. Myers has spent the past decade studying and testing high-strength concrete and other innovative concrete systems for implementation.

Myers and his team found that using high-strength, self-consolidating concrete can either extend the span length of the girders — a structure’s main support member — or reduce the number of girder lines needed in a given span. Self-consolidating concrete is a high- performance concrete that can flow easily into tight and constricted spaces without separation or the need of vibration to remove trapped air. Myers believes the material will also cost less to maintain and last longer than conventional concrete.

Honoring new academy members

In October, 12 alumni and friends were inducted into Missouri S&T academies. Academy membership recognizes careers of distinction and invites members to share their wisdom, influence and resources with faculty and students. Some academies hold induction ceremonies in the fall, others in the spring.

Boosting cyber-physical security

A wide array of complex systems that rely on computers — from public water supply systems and electric grids to chemical plants and self-driving vehicles — increasingly come under not just digital but physical attacks. Bruce McMillin, professor and interim chair of computer science at Missouri S&T, is looking to change that by developing stronger safeguards […]

MXene discovery could improve energy storage

In spite of their diminutive size, 2-D titanium carbide materials known as MXenes are “quite reactive” to water, a discovery S&T researchers say could have implications for energy storage and harvesting applications such as batteries, supercapacitors and beyond. Their findings were published in 2018 in the American Chemical Society journal Inorganic Chemistry.

A faster charge for electric vehicles

One drawback of electric vehicles (EVs) is the time it takes to charge them. But what if you could plug in your EV and fully charge it as quickly as it takes to fill up a conventional car with gasoline? Missouri S&T researchers, in collaboration with three private companies, are working to make speedy charging […]
