Creep is a major research issue in fibre reinforced concrete. Many test methods exist to assess creep on structural elements subjected to mid or long-term flexural loading. Most of them are performed on notched beams on isostatic support. Asquapro launched an experimental program to assess the creep behaviour of fibre reinforced sprayed concrete (FRSC). A test method was especially designed to take into account the specifications of FRSC for underground support (unnotched specimens under statistically indeterminate support conditions). The aim of this paper is to present the results of this programme after one year of testing. Differences between fibres are clearly identified, within the same type of fibres or between different types (metallic/polymeric). A comparison is also made with specimens reinforced by a wire welded mesh.
