Graphene-infused concrete would be twice as strong, more water resistant than current mixes

Scientists at the University of Exeter in the U.K. are developing an environmentally friendly composite material by incorporating concrete with graphene to create a material that is more than twice as strong and four times more water resistant than existing concretes, and produces less greenhouse gas emissions, The Guardian reports. Graphene is made up of a single […]

Purdue researchers testing stronger cellulose-infused concrete on Calif. bridge

Researchers at Purdue University have found a way to make concrete stronger by infusing it with cellulose nanocrystals, byproducts generated from wood, and will test it on a bridge that will be built in California this spring, according to a news release from the Purdue Research Foundation. At press time, the exact bridge where the cellulose-infused […]

New smart memory alloy designed to replace rebar in bridges as earthquake reinforcement

Researchers at the University of British Columbia (UBC) Okanagan have developed smart memory alloys for use in concrete bridges in earthquake-prone areas that they say are safer and more cost-effective than steel rebar. “Conventional steel rebar reinforcements have been used for years in building structurally sound bridges,” said Shahria Alam, associate professor of engineering and […]

Mont. university develops affordable ultra-high performance concrete for state DOT

Researchers at Montana State University (MSU) have developed an ultra-high performance concrete that is approximately five times stronger than regular concrete, according to a university press release. The Montana Department of Transportation (MDT) asked Michael Berry, a professor in the Department of Civil Engineering, if the university’s Norm Asbjornson College of Engineering could help develop a more affordable, non-proprietary […]

New concrete mixture would allow roads to resist corrosion from road salt

Deicing salt is used on roads every winter to improve driving conditions, but the calcium chloride salt commonly used in this application reacts with the calcium hydroxide in concrete, forming a chemical byproduct called calcium oxychloride that causes roadways to degrade, crack, and crumble. According to a Drexel University press release provided to Phys.org, Yaghoob Farnam, a civil engineer, […]

Acid mine drainage may be the answer for bendable, more durable concrete

The Eastern Pennsylvania Coalition for Abandoned Mine Reclamation (EPCAMR) in Ashley donated approximately 180 gallons of acid mine drainage from Solomon Creek boreholes in Hanover Township to the University of Michigan to help with its research into a bendable, more durable concrete, The Times-Tribune reports. Robert Hughes, executive director of EPCAMR, told the news agency he hopes to […]

Canadian researchers say bridge safety codes lead to overbuilt bridges, higher costs

A recent study of bridge types and their design requirements conducted by researchers at the University of British Columbia (UBC) Okanagan concluded that, in building bridges to withstand the force of an earthquake, they are being overbuilt, driving up construction costs. “We’ve determined it’s very unnecessary to design a structure with that much reinforcement,” UBC professor Shahria […]
