| Povzetek: | The manuscript provides long-term microstructural study on as-collected wood biomass ash (WBA) from a pulverised fuel combustor. Analytical methods, including isothermal calorimetry, X-ray powder diffraction, thermogravimetric analysis, and mercury intrusion porosimetry, were used to assess reaction kinetics, phase development, and porosity. Results show that WBA in- creases water demand due to its irregular particle morphology and high content of unburnt carbon and carbonates, causing a dilution effect that delays hydration reactions and extends the induction period. Microstructural analysis revealed significant changes in porosity, with an in- crease in pores between 0.01–0.05 μm during early hydration. As a result, early mechanical strength is reduced. Over time, the pozzolanic activity and carbonation of WBA enhance compressive strength, improving long-term performance. The study highlights the potential of WBA as a sustainable cement substitute and emphasises the need for further research to optimise its integration into concrete applications and assess its durability in various environments. |
