Japan uses highly elastic concrete to resist earthquake threat

< P > < FONT face = Verdana > According to media reports here on the 28th, Japan's Kashima Construction Company has developed a highly elastic and flexible concrete that can help buildings withstand the threat of earthquakes. The company is working on ways to take full advantage of the material's properties.

< P > < FONT face = Verdana > The concrete reportedly contains a hair-thick synthetic fiber commonly used to make tires. This fiber can prevent cracks from expanding when the concrete is subjected to external forces such as extrusion.

< P > < FONT face = Verdana > Tetsushi Kanda, an engineer at Kashima Construction Company, said that buildings built with this kind of concrete "have no problem at all even if there is a big earthquake.".

< P > < FONT face = Verdana > Two buildings in Japan have been built with this concrete, and about 100 other buildings and infrastructure have been reinforced with this concrete, the report said.

< P > < FONT face = Verdana > Kanda said that after 10 years of research and development, the concrete has been promoted since 2003. Its price is 10 times that of ordinary concrete, and it currently accounts for only 0.1% of the domestic concrete market in Japan. "We're looking for ways to make the most of the material's performance while keeping the price down," he said.
