The aim of this study was to investigate the concept of lower punch vibration as a possible approach to densify the powder bed within the die of a rotary tablet press. Therefore, a laboratory vibration equipment was developed to obtain a better understanding of the performance characteristics and effects of a pneumatically generated vibration syste...

The mix design of ultra-high performance concrete (UHPC) is complicated by the presence of many “ingredients.” The fundamental packing density allows a simpler mix design with fewer ingredients to achieve optimum packing density and dense microstructure. The optimum particle grading increases the flowability of UHPC and eliminates entrapped air. Th...

Het Lisse effect, Wieringermeer effect en omgekeerd Wieringermeer effect zijn de oorzaak van onverwacht snelle en grote grondwaterstandsschommelingen. Het Lisse effect is het gevolg van luchtinsluiting tussen het infiltratiefront en het freatisch vlak. Het Wieringermeer en omgekeerd Wieringermeer effect zijn het gevolg van wederzijdse conversie van...

In this study an ultra-high performance mortar was optimized. The interaction curve of two types of densified silica fume (white and grey) with cement was determined based on the Marquardt method. It was seen that the white silica fume increased the packing density more than the grey silica fume. Consequently, this enabled us to lower the water-to-...

The temperature dependence of the matric potential of soil water was investigated as part of a study of the effects of climate change on soil physical properties. Undisturbed samples of topsoils were collected in cylinders. The pore water suction near the center of each cylinder was measured using two miniature tensiometers. The temperature of the ...

The paper deals with the methods for evaluation of the hydro-elastic interactions which appear during the violent sloshing motions inside the LNG tanks. The complexity of both fluid flow and the structural behavior (containment system + ship structure) do not allow for fully consistent direct approach according to the present state of the art. Seve...
