Utilisation of Wood Ash in Cement-Based Materials

Sigvardsen, Nina Marie

Technical University of Denmark, Department of Civil Engineering — 2020

Wood ashes originating from combustion of wood and woody biomass were investigated with the aim of utilising wood ash as a partial cement replacement. The physicochemical properties of wood ashes varied significantly depending on the combustion technique and temperature, the type of woody biomass used etc. Multivariate data analysis of chemical compositions was performed to determine which production parameters yielded the wood ash most suitable for utilisation as a partial cement replacement in cement-based materials. The standards EN 450 [1] and EN 197 [2] were used for the assessment of ...

Impact of production parameters on physiochemical characteristics of wood ash for possible utilisation in cement-based materials

Sigvardsen, Nina M.; Kirkelund, Gunvor M.; Jensen, Pernille E.; Geiker, Mette R.; Ottosen, Lisbeth M.

Resources, Conservation and Recycling — 2019, Volume 145, pp. 230-240

to an increase in the production of wood ash (WA). Multivariate modelling was used to identify the link between production parameters and the physiochemical characteristics of different WAs and to determine which production parameters result in the WAs most suitable for utilisation in cement-based
