Abstract: The main propose of this paper is to assess the minimum duration of in situ measured data to be use in creep and shrinkage models in order to obtain sufficient accuracy in long-time predictions. A brief description of the experimental procedure used to measure creep and shrinkage in field conditions is done. A methodology to analyse the evolution of experimental data, including its variability is also presented. This methodology is then applied to initial sets of measured data with different duration.
