Chemical Composition, Thermal Analysis and Pozzolanic Activity of Biomass Ash from Miscanthus.

In this contribution, we would like to show that biomass ash coming from combustion of Miscanthus Giganteus can be used for fabrication of blended cement-based composites due to its high pozzolanic activity and suitable chemical nature. Biomass ash composition was characterized using X-ray fluorescence and energy dispersive spectroscopy. The phase composition was analyzed in detail by X-ray diffraction. Moreover, the thermal stability was analyzed using simultaneous thermal analysis. In the next step, the pozzolanic activity was analyzed using modified Chapelle test. Potentiometric method was used for pH measurement. Since the biomass ash was pozzolana active, it is potentially suitable as a pozzolana active admixture in cement, lime and alkali activated aluminosilicate composites. [ABSTRACT FROM AUTHOR]
