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.

Study on workability and mechanical strength of low cement ultra-high performance concrete with ultrafine quartz powder as alternative material under high temperature curing

Case Studies in Construction Materials
High CO2 emission has been a key issue that needs to be addressed for the widespread use of ultra-high performance concrete (UHPC). In this study, low cement UHPC was prepared by using ultrafine quartz powder (UQP) as a replacement material for cement ...
