Shifting nanoparticles cause creep

Science News : Concrete creeps. And now scientists think they know why.New measurements suggest that the rearrangement of nano-sized concrete particles is responsible for the way buildings, bridges, and other load-bearing concrete structures deform over time, a process technically known as “creep.” The new insight could allow engineers to make stronger and longer-lasting concrete, researchers report in a study to be published online in the Proceedings of the National Academy of Sciences.
