I am not familiar with ABAQUS, but I know that Code_aster http://www.code-aster.org/V2/spip.php?rubrique2 proposes some relevant model for concrete creep. It is a free and opensource code, maybe is it suitable to help you

Shahram Mousavi

Similar to other general purpose programs, ABAQUS is not designed

to handle concrete creep.
