SEOUL – Seoul will demonstrate technologies such as photocatalyst-based particle reduction and safety analysis to measure the tensile strength of old prestressed concrete that was used for urban highway bridges.

Particles, also called fine dust, are a cloud of microscopic pollution particles that remain in the air. This air pollution includes nanoscale heavy metals and other substances that can pose health risks. Fine dust is primarily created by combustion, while particulate matter is commonly found on construction sites.

Prestressed concrete (PSC) is a form of concrete primarily used in the construction of a bridge. It is compressed during production to have a higher tensile strength than normal reinforced concrete.

Seoul Facilities Corporation (SFC), the operating agency of the capital’s public facilities, works with the Korea Agency for Infrastructure Technology Advancement, a government-funded technology institute to verify the structural integrity of tunnels and bridges on highways urban areas and reduce fine dust.

“With the recognition of the social problems caused by obsolete public infrastructure in the United States and Europe, we need to prepare deeply for the future so that policies and technologies can help South Korea’s infrastructure to maintain their role as the foundation of people’s livelihood and economy, “SFC Chairman Cho Sung-il said in a statement Oct. 15.
