Sažetak
The European Union plans a complete shutdown of coal power plants by 2030. It consequently leads towards significant increase of wood biomass usage as renewable energy source, hence increase of wood biomass ash (WBA) amount. Landfilling expenses and lack of new landfills set of the need for reuse of WBA. Partial replacement of cement could be one of the possible solutions for WBA use in the concrete industry. Lack of regulations and standards for WBA usage in cement mixtures, as there are for coal fly ash, emphasize the need to determine the potential of WBA use as a cement replacement. The properties of WBA vary depending on the type of used wood biomass, combustion technology and location of the ash collection. This paper is focused on the effect of using WBA in different contents on the physical properties of cement composites (workability, setting time and soundness).
