Description
| - This paper describes the procedure for checking the suitability of chemical admixtures for UHPC by means of chosen testing methods performed on cement pastes. The unavoidable parts of UHPC are the active or passive admixtures (micro silica, finely ground slag, ashes from electricity supply industry, etc.) that significantly act in the whole process and effect both rheological properties of fresh composite materials and physical-mechanical properties of hardened composite materials. The verification of suitability of chemical admixtures and their effective compatibility in the whole system cement-admixture-additive-water is also essential in this case.

- Příspěvek popisuje postup pro kontrolu vhodnosti přísad pro UHPC prováděných na cementových pastách. Nevyhnutelná část UHPC jsou aktivní nebo pasivní příměsi (mikrosilika, jemně mletá struska, popílky, atd.), které se významně podílí na reologickém chování čerstvého betonu a na fyzikálně-mechanických vlastnostech ztvrdlého betonu. Ověření vhodnosti přísad a jejich efektivita v systému cement-příměs-přísada-voda je také podstatou tohoto projektu. (cs)
