"Proceedings of the Ninth International Conference on Creep, Shrinkage, and Durability Mechanics (CONCREEP-9), held in Cambridge, Massachusetts, September 22-25, 2013. This collection contains 59 invited and peer-reviewed papers on the deformation under load of concrete and concrete structures. These papers dissect the physical origin of creep and shrinkage of concrete and propel this knowledge from the scale of a few atoms to full-scale engineering applications. Researchers from physics and engineering disciplines working on the next generation of science-enabled engineering solutions, along with scientists doing related work with soft matter, glass, and computational materials, will find that these papers present the state-of-the-art in concrete creep, shrinkage, and durability mechanics. --
