Experiences from 14 Years of Creep Testing of Steel and Polymer Fiber Reinforced Concreted to have a higher impact for polymer macro fibres than steel fibres. All setups have been tailored to specific applications and thus vary in size, applied load and pre-cracking deformation. The same holds for setups used by other research groups so that it is difficult to compare results. Based on

Tensile Creep of Cracked Steel Fibre Reinforced Concrete: Mechanisms on the Single Fibre and at the e load up to at least 50 % of the ultimate load after which the pull-out creep increases non-linearly. This can be ascribed to micro-cracking around the hooked-end of the fibre. Lastly, it is postulated that the interfacial transition zone between the fibre hooked-end and the concrete matrix plays a

Behavior of Cracked Cross-Section of Fibre Reinforced UHPFRC Under Sustained Load was used for a direct observation of the fibre inside the concrete. A correlation between experimental results with large scatter and specimen fibre distribution and orientation is sought in this way.

Effect of Beam Width on the Creep Behaviour of Cracked Fibre Reinforced Concreteand the sustained bending stress was equal to 60 % of the stress .. of each prism. The results show that the specimen width has a minor effect on the results of creep tests in cracked state but the variability increases when the width decreases.
