Utilization of aluminium dross as a main raw material for synthesis of geopolymer
Keywords:
Aluminium dross, Bagasse ash, GeopolymerAbstract
Aluminium dross contains both small particles and large agglomerates, where the recyclable part is the large agglomerates with high aluminium metal content. The residual Al dross is unrecyclable small particles with very low aluminium metal content. In this research, the residual Al dross from the aluminium recycle industry and the bagasse ash from a biomass power plant were used as main raw materials for geopolymer fabrication with alkaline solutions (Na2SiO3 and NaOH) using in the typical geopolymerization process. After mixing with alkaline solutions, the mixtures were uniaxially pressed into a cylinder die. The samples were cured for 3, 7, 14 and 28 days at the room temperature. The compressive strength and thermal conductivity of geopolymers were measured. In addition, scanning electron microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) was employed in order to study the microstructure and the structure change of the geopolymer products.
