Abstract: An investigation is carried out on the possibility to use self-compacting concrete as concrete for slipform operations. The traditional way to carry out slipforming is by placing concrete layers at regular intervals into the form, which can often result in a dry concrete surface before the next concrete layer are placed. Tests are carried out where the effects of dry surface on bonding between the layers are determined. Also the friction that occurs during lifting of the slipform panel is tested. The results show that the tested self-compacting concrete has obtained a good bond between the layers, even when placing is carried out on a dry surface. Also the tests carried out in a slipform rig show that the self-compacting concrete has approximately the same maximum friction level as for vibrated concrete. The results indicate that self-compacting concrete can be considered to be used during slipforming, but more tests are necessary in order to make clear conclusions and to identify any limitations.
