The Influence of Vacuum Mixing on the Porosity of Ultra ...

The influence of vacuum mixing on the porosity of ultra-high performance concrete (UHPC) was examined. For this reason, test specimen with a typical mix composition for UHPC were prepared and cured in six different ways. The pore size distribution and the total porosity were determined by the use of mercury intrusion porosimetry (MIP). The results show that the total porosity of vacuum mixed ...

Mar 18, 2009  At present the use of ultra high performance concrete (UHPC) is limited to a small number of special applications. This is essentially due to the time needed to blend the UHPC mix which is considerably longer than required for ordinary concrete. The present investigations aimed at the determination of the composition features which result in the longer mixing time of UHPC.
