Abstract:

Thermal and visco-elastic effects are more pronounced in early age concrete (1 to 7 days). This is due to the presence of free water and un-hydrated cementious particles. It is common practice to load the structural members during this time in order to meet the tight construction schedule. As a result, regions of high stress concentrations, such as anchorage zones in post-tensioned (PT) members, experience higher time dependent strains. This paper discusses the early age concrete effects and the predictions of early age creep strains using B3 model. A simple cylindrical specimen is considered for the analysis. © 2011 Taylor & Francis Group, London.
