Abstract

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 materials. Based on the multivariate model partial least square, WA originating from circulating fluidised bed combustion of wood chips made from whole trees is the optimal type of WA when utilised as a supplementary cementing material with pozzolanic activity. WA originating from the combustion of wood chips made from whole trees is the optimal type of WA when utilised as a supplementary cementing material with hydraulic activity. Furthermore, the combustion method and type of ash were seen to have the largest influence on the physiochemical characteristics
of WAs compared to the other production parameters included in this study.
