Did you know recycled human hair has many industry uses? As you might expect, beauty trends have fueled growth in the global hair business. But could those clippings — the ones often found on the floor of a hair salon — help repair dilapidated bridges and buildings across Kentucky and beyond? A research team in the College of Engineering at the University of Kentucky is leading the charge to answer that very question.
Swanson School of Engineering researchers develop self-sensing metamaterial concrete for smart infrastructure systems
The cement industry emits more than 3 gigatons of carbon dioxide worldwide from the manufacturing of about 4.5 gigatons of cement every year because of its carbon-dioxide- and energy-intensive processing. This amount of cement is necessary to produce the concrete that shapes modern infrastructure.
A world-first project to create ‘self healing concrete’ using treated sludge, will not only automatically repair cracked sewer pipelines, but also help the environment by reusing waste that normally ends up in landfill.

NUS researchers have taken a waste product from construction sites in Singapore and upcycled it into a raw material for ultra-high-performance concrete. Their method could help reduce the carbon footprint of concrete and also cut the cost of production. This is the first time low-grade waste clay has been used as fillers in concrete.
The Penn State and materials research communities are mourning the loss of Della M. Roy, emeritus professor of materials science and a founding member of the Penn State Materials Research Laboratory (MRL), now the Materials Research Institute (MRI). Della died on March 27 at age 94. Della was known as an international leader in the field of cement and concrete research and for being a groundbreaker for women in science.
Concrete sewer pipes around the world are most likely to fail either because their concrete is not strong enough or because they can’t handle the weight of trucks that drive over them, a new study indicates.
Can antibiotic-resistant bacteria escape from sewers into waterways and cause a disease outbreak? A new Rutgers study, published in the journal Environmental Science: Water Research & Technology, examined the microbe-laden “biofilms” that cling to sewer walls, and even built a simulated sewer to study the germs that survive within.
Secrets to cementing the sustainability of our future infrastructure may come from nature, such as proteins that keep plants and animals from freezing in extremely cold conditions. CU Boulder researchers have discovered that a synthetic molecule based on natural antifreeze proteins minimizes freeze-thaw damage and increases the strength and durability of concrete, improving the longevity of new infrastructure and decreasing carbon emissions over its lifetime.
