  • Biomass ash characterization and its use in cement-based materials
    Korat, Lidija, 1986- ...
    This paper presents possibilities of use Slovenian ash from co-buring biomass by replacing a Portland- slag cement CEM II/A-S 42,5 R with the equivalent mass of 5, 10 and 15 wt.% of biomass ash. The ... physical properties and chemicalcomposition of fresh and storage biomass ashes were tested. Characterization of the biomass ashes samples was also conducted by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The research pastes were prepared and mechanically, physically and mineralogical characterized. Results showed that fresh biomass ash is less appropriate then altered ash for production of stable mortars, due to high quantity of free CaO. In cement based pastes with higher amount of added biomass ash the mechanical properties decrease after 28 days, than at the pastes with lower amount of biomass ash.
