In this paper, we demonstrated that wooden chips ash can be further processed and selected products of its treatment can be used as additives in magnesium phosphate cement composites. Wooden chips ash, as well as obtained products, were analysed by XRF, XRD, SEM, EDS, STA. Also, the particle size of the obtained fractions was analysed using laser diffraction. Basic structural properties, bulk density, specific density, total open porosity and pore size distribution of prepared composite material in comparison to the reference were measured. In addition, mechanical properties were also tested. The newly developed composite with incorporated fractions of wood chips ash showed acceptable structural and mechanical properties that were almost unchanged compared to the reference sample without any biomass-based additives.
