Impact of production parameters on physiochemical characteristics of wood ash for possible utilisation in cement-based materials
Sigvardsen, Nina Marie; Kirkelund, Gunvor M.; Jensen, Pernille E.; Geiker, Mette Rica; Ottosen, Lisbeth M. (Journal article; Peer reviewed, 2019)Energy production is reorganised to mitigate the pressure on the global environment. This reorganisation leads to an increase in the production of wood ash (WA). Multivariate modelling was used to identify the link between ... -
Phase development and mechanical response of low-level cement replacements with wood ash and washed wood ash
Sigvardsen, Nina Marie; Geiker, Mette Rica; Ottosen, Lisbeth M. (Peer reviewed; Journal article, 2020)A significant increase is seen worldwide in the amounts of wood ashes (WAs) produced by the heating and power industry. This study investigates the potential utilisation of two different WAs as low-level cement replacements, ... -
Reaction mechanisms of wood ash for use as a partial cement replacement
Sigvardsen, Nina Marie; Geiker, Mette Rica; Ottosen, Lisbeth M. (Peer reviewed; Journal article, 2021)An increase in the produced amounts of wood ashes (WAs) is seen worldwide. In this study, the potential use of two representative WAs as a partial cement replacement is investigated. The WAs originate from combustion of ...
