Novel ultra high performance concrete mixing technology ...

Jan 18, 2021  The premise that “high-performance concrete must be produced, delivered and placed in the same way as usual concrete” does not necessarily apply to modern ultra high performance concrete (UHPC). Rotating drum or pan mixers traditionally used for concrete do not always provide sufficient mixing efficiency to produce high quality UHPC.
