Creep is the gradual structural deformation in concrete under a load. While creep does not necessarily cause concrete to fail or break apart, it is known to impact on the durability of concrete structures -- but what causes it? This research brief presents foundational work toward understanding the mechanics of creep at the nano-scale. Researchers studied the phenomenon in a model material: metallic glass. Cement paste is a more complicated structure, but the understanding of metallic glasses could allow researchers to begin studying how creep occurs in the heart of cement paste, C-S-H. Read more.
