报告摘要：
       In this presentation, causes and mechanisms of early-age deformation in cementitious materials, including plastic shrinkage, drying shrinkage, thermal deformation and autogenous deformation will be introduced.
       For each of those, recent developments in measuring techniques and analysis approaches by the speaker and his research group will be illustrated. Special emphasis will be on methods to reduce early-age deformation and mitigate the cracking risk of concrete structures at early-ages, as well as on methods to study moisture distribution in cementitious materials at early ages (neutron tomography and multi-contrast X-ray tomography).

报告人简介：
       Pietro Lura is Head of the Concrete and Construction Chemistry Laboratory since 2008 and professor at ETH Zurich, Institute of Building Materials, since 2011. He received his MS in 1998 from the University of Brescia, Italy, and his PhD in 2003 from the Delft University of Technology, The Netherlands. He has been assistant professor at the Technical University of Denmark (2003-2006), visiting researcher at the National Institute for Standard and Technology (2002) and at Purdue University (2005), and patent examiner at the European Patent Office in Munich, Germany (2006-2008).
       His research interests include hydration and early-age properties of concrete, in particular microstructure development, shrinkage, setting, early-age cracking and internal curing. In these fields he has done important contributions to both understanding of the fundamental mechanisms and to advancement in the state of the art. His work on measuring techniques of autogenous deformation earned him two awards from the Transportation Research Board, the Bryant Mather Award in 2006 and the Fred Burggraf Award in 2007. For his work on internal curing he received the American Concrete Institute Wason Medal for Materials Research in 2007. He received for the second time the ACI Wason Medal in 2009 for his contribution to the understanding of the mechanisms of plastic shrinkage cracking. In 2009 he also received RILEM L'Hermite Medal in recognition of his outstanding contribution to the study of the early-age behavior and volume instability of cement-based materials.
