Consequences of an adjusted slip layer thickness for the hardened properties of UHPC [PDF]

, 2017
The pumpability of a concrete mixture cannot be described by one “single parameter”. The mixture composition, the pump equipment, the pumping pressure,… these parameters all affect the pumpability of a mixture and the ability to form a lubrication layer.
