In recent years, security experts have come to realize the danger of electromagnetic pulse attacks, powerful weapons that can completely destroy power systems and put millions of people at risk. At present, researchers have recently developed a conductive concrete, which can be used as a shielding layer to avoid being attacked by electromagnetic pulse weapons.
This conductive concrete can absorb and reflect electromagnetic waves, thus protecting the building's internal power system. Designers say that in the future, this technology can be used in new building structures, or improve existing buildings by spraying. The technology was designed by a team of engineers at the University of Nebraska-Lincoln in the United States. It is reported that the technology has been used to melt ice and snow on roads before. But they have found that the technology has other important uses-it can effectively block electromagnetic energy.
Christopher, a professor in the Department of Civil Engineering, pointed out that electromagnetic pulse weapons (EMP) are very lethal electronic devices, and we have found that dissipating wave energy can eliminate their threat. Our newly developed conductive concrete can shield buildings from electromagnetic pulse.
This conductive concrete is able to conduct electricity, using magnetite instead of some standard concrete materials. Magnetite is magnetic and can absorb microwaves. At the same time, the concrete also contains carbon and metal substances, which help to improve its absorption capacity and reflect electromagnetic pulses.
Researchers point out that this method is more effective than traditional shielding techniques, which rely on higher-cost metal coatings. In the future, this technology can be applied to commercial, military and financial fields, making other important building structures safer.
