The world's foremost resource on decorative concrete
CarbonCure Technologies, a Halifax-based startup that has developed the technology to recycle carbon dioxide gas back into solid concrete.
A researcher is trying to give cement sensing properties with applications in the oil industry.
The science magazine Rubin reports that engineers at Germany’s Ruhr-Universität Bochum have developed a shotcrete that can render tunnels, bridges and other structures more resistant against fires and explosions.
A new report from Phys.org explains how subatomic particles known as muons are being used to probe the structure of concrete. This is a useful ability because building materials such as pipes and concrete that are part of our energy infrastructure corrode and wear thin or degrade over time. Scientists were seeking a better way to be warned of infrastructure deterioration before it becomes a problem and found that these particles work.
Concrete made using an industrial by-product has shown better fire endurance than traditional concrete when exposed to fires of nearly 1000 degrees Celsius.
A research team has created a form of concrete that, remarkably, can be made without water and using materials that are widely available on Mars.
Scientists at the Swiss Federal Laboratories for Materials Science and Technology (EMPA) have added polypropylene (PP) fiber to a concrete mix. The technique allows water vapor to escape, preventing pressure from building inside the concrete, making it more fire-proof.
The website Phys.org revealed new research into whether the structure that forms when water, gravel, sand and cement powder are combined is a continuous solid, like metal or stone, or an aggregate of small particles.
Michael R. Jensen is CEO and artist at Atlanta Concrete Artist, billed as a purveyor of “exotic designer flooring.” He recently completed an epoxy garage floor for a car enthusiast in Sandy Springs, Ga.
Randall Klassen, of Winnipeg, Manitoba, sent us these photos of a monolithically poured concrete "bridge" over concrete "water" he constructed for Seven Oaks School Division, in northwest Winnipeg.
