Cement company "Hoshinobu Hiroshi" communication World's first development of special concrete to prevent power failure

The cement company ``Sung Shin Yohai'' has developed a special concrete for the first time in the world to prevent communication and power failures caused by North Korea's ``Electronic Air Wave (EMP) Terrorism'' and solar wind. Sungshin Cement announced on the 17th that it has developed a special concrete with EMP shield function and has successfully produced a prototype. It is said that the United States and Europe, which have excellent national defense technology, have not been able to commercialize concrete with EMP shielding functions. Unlike ordinary concrete, this concrete blocks almost 100% of electromagnetic waves because it uses aggregates containing metal components such as iron and copper. An official from Sungshin Cement said, "After analyzing hundreds of types of metal aggregates, we found a material with high conductivity, the best electromagnetic wave reflection effect, and good cost performance." It took years," he said. Interest in the EMP shield increased because North Korea launched a super-powerful nuclear EMP attack in its sixth nuclear test in 2017. It was triggered by warning that there is. EMP attacks can destroy electronic devices such as mobile phones and computers, cause damage such as power outages and communication disruptions, and can cause major weapons to malfunction. Sungshin Cement emphasized that it can prevent not only EMP attacks but also communication disruptions caused by solar wind caused by sunspot explosions on the surface of the sun. The electromagnetic wave shielding performance of existing general reinforced concrete is 10~20dB (electromagnetic wave unit) or less, and there is no EMP shielding function. On the other hand, the EMP shield concrete developed this time has a shielding performance of 40-55 dB with a wall thickness of 100 mm, 55-70 dB with a wall thickness of 200 mm, and over 80 dB with a wall thickness of 300 mm. Sungshin Cement said, ``80 dB effectively means 100% shielding. can be prevented,” he said. Yoon Chul-hyun, head of Sungshin Yohye Technology Research Institute, said, "The newly developed EMP shielding concrete technology can be used not only in military facilities but also in the private sector, especially national communication networks, broadcasting stations, railway control and power plants, and financial networks. It is possible to protect information and communication infrastructure facilities such as those in Japan and large hospitals with many electronic devices that are essential for life support from EMP attacks." Yoon also emphasized, “With the domestic production of EMP shield technology led by the United States and Europe, we can expect security technology import substitution and technology export effects.”
