A company in Japan is developing a new concrete that will extend the life of concrete to more than 200 years. That is more than double the current lifespan of concrete today.
According to an article in the San Francisco Chronicle, the heavy industry company plans to commercialize the technology by the end of this year or later. The company says the technology is expected to reduce maintenance and renewal costs for infrastructure such as roads, bridges and tunnels.
In a recent article from For Construction Pros they write: “When traditional concrete is poured, air comes into contact with the concrete forming bubbles that result in holes on the surface of the concrete. Over time, those holes are penetrated with rainwater, salt and more causing the reinforced steel rods to corrode and the concrete to crack.”
