In potentially transformative research for both the recycling and concrete industries, a City College of New York civil engineering team is developing a glass powder to replace cement in the production of concrete.
Phys.org announced research that could lead to a way to light roads, highways or bicycle lanes without electricity.
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.
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.
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.
The manufacturing process which produces ordinary portland cement, the ubiquitous ingredient in the concrete used around the world, is a major contributor to greenhouse gas emissions. New research suggests that portland cement can be produced with no carbon dioxide emissions.
An electrical engineer at Missouri University of Science and Technology is using microwave energy to test concrete and rehabilitated aluminum, and in the future her work could lead to safer bridges and aircraft parts.
Battelle scientists have developed a tiny bead, the Battelle Smart Corrosion Detector bead, that not only detects corrosion but delivers a payload to help heal the microscopic cracks that rust creates.
Concrete made using an industrial by-product has shown better fire endurance than traditional concrete when exposed to fires of nearly 1000 degrees Celsius.
Cement production contributes an estimated 6 percent of global greenhouse-gas emissions, and some scientists are trying to chip away at that pollution problem. Two start-ups, one in Canada and another in Arizona, are among the newer entries in the effort to produce cleaner cement and concrete.
The New York Times recently reported that hemp fibers are being worked into concrete to form a mixture called hempcrete. While no one would want to smoke this stuff, it does seem particularly useful as a building material.
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.
Europe's first solar concrete wall appears at Reckli's headquarter in Herne, Germany. The structure's smart facade combines various concrete structures and a solar energy generating film.
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 researcher is trying to give cement sensing properties with applications in the oil industry.
CarbonCure Technologies, a Halifax-based startup that has developed the technology to recycle carbon dioxide gas back into solid concrete.
An Australian company is harvesting blast furnace waste and converting it into a new product to make cement in China, where 60% of the world’s iron waste is found.
Researchers have successfully reinforced concrete with plastic waste, paving way for the first large-scale sustainable construction practice.
The reason concrete is so strong is elemental . . . according to researchers at Rice University, studying friction on materials such as concrete has provided the answer.
Interesting explanation for why ancient mortar has lasted long.
