The ecological impact of UHPC is driven by the high cement content in the recipe with more than double the amount needed in comparison to normal strength concrete (NSC). Substitution of cement in the recipe by less-energy-intensive hydraulic concrete additives is investigated on its influence to the concrete properties and its environmental impact parameters calculated for the different UHPC recipes. 000002152 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000002152 653__ $$aUHPC, sustainability, supplementary cementitious materials, granulated blast furnace slag, environmental impact 000002152 7112_ $$aFirst International Conference on Concrete Sustainability$$cTokyo (JP)$$d2013-05-27 / 2013-05-29$$gICCS13 000002152 720__ $$aRANDL, Norbert$$iBAUMGARTNER, Erwin$$iOFNER, Sandra$$iSTEINER, Thomas 000002152 8560_ $$ffischerc@itam.cas.cz 000002152 8564_ $$s1544589$$uhttp://invenio.itam.cas.cz/record/2152/files/S2-7-4.pdf$$y Original version of the author's contribution as presented on CD, . 000002152 962__ $$r2053 000002152 980__ $$aPAPER
