Abstract: Predicting the creep deformation is an important aspect in the evaluation of the long term behavior of concrete. The main objective of this study is to create a database of creep results which will permit a more generalized study of the creep behavior of SCC and broader statistical analysis in order to evaluate the overall applicability of the actual estimating models to SCC. In this study, experimental creep results for self consolidating (SCC) and conventional concrete (CC) are compiled from 11 published investigations into a database.
The database includes 57 SCC mixtures and 15 CC mixtures. The experimental results included in the data base proceed mainly from the various conferences on SCC and from other published articles.
The creep strains for the concrete mixtures are calculated using the following predictions models: CEB-FIP 1990[1], ACI 209[2] , B3[3] and GL2000[4]. The calculated creep strains are compared with the experimental results in order to evaluate the applicability of the four models to SCC.
