Abstract: 
The application of ultra-high performance fibre reinforced concrete (UHPFRC) in structures entails in general the application of precast elements. Therefore the issue of how to join the elements is of highest importance. Dry joints allow the transfer of compression and shear forces, whereby the magnitude of the transferable shear force depends amongst others on the cohesion factor and the friction coefficient. Values for these are stated in the respective design codes depending on the roughness of the joint surface. However, the classification of the surface roughness is often not very exact so that an experimental verification of the cohesion factor and the friction coefficient is advisable.
Lafarge commissioned the Institute for Lightweight Structures and Conceptual Design (ILEK) at the University of Stuttgart to carry out an experimental investigation to determine the effect of different surface roughness classes on the load-bearing behaviour of dry joints between precast elements made of UHPFRC.
