MICROSCOPIC AND PHASE ANALYSIS OF CEMENT PASTE CONTAINING WASTE MICRONIZED MARBLE POWDER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The article focuses on the impact of waste marble powder on resulting cement composites. We investigate of influence waste marble powder on the hydration process and hence the resulting phase composition. The hydration ...
Influence of oxygen and argon plasma treatment on wettability and surface morphology of polypropylene microfibers
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
The surface treatment of polypropylene microfibers by plasma processing in oxygen and argon was studied with the motivation to increase their cohesion with the cement matrix. By plasma treatment, it is possible to modify ...
