Research on Method of Separating Autogenous Shrinkage from Thermal Deformation of Concrete at Early Ages

Abstract:

In order to separate early-gae autogenous shrinkage from thermal deformation, it is the key to measure accurately thermal expansion coefficient of concrete at early ages. By analysing deeply the research status of early-age thermal expansion coefficient of concrete, the influences of temperature history on early-age autogenous shrinkage and the selection of thermal expansion coefficient are discussed. Moreover, based on the existing methods of separating early-gae autogenous shrinkage from thermal deformation, the more reasonable two-phase separating method considering concrete ages is provided.
