Researchers File Patent for Fire-resistant Concrete

fire resistant concrete

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.

Using Muons from Cosmic Rays to Find Degrading Concrete

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.

New Formula for High-Strength Shotcrete to Protect Tunnels from Fires and Terrorist Attacks

Fire-proof shotcrete Concrete Decor Magazine Phys.org reported that the science magazine Rubin published research conducted by engineers at Germany's Ruhr-Universit├Ąt Bochum who have developed a shotcrete that can render tunnels, bridges and other structures more resistant against fires and explosions. The new formula enhances concrete with 140 kilograms of steel fibers per cubic meter, a figure that was thought to be impossible for shotcrete. 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.
