Chemical and Mineralogical Characterization of Biomass Ashes for Soil Reinforcement and Liner Material

Mineralogical and chemical evaluations are necessary to investigate the background origins of materials. In terms residues commonly produced around world, ashes biomass stands out for its high calorific capacity use energy production at thermoelectrical facilities. Given current sustainability issues new demands from society, soil pine in Castelo Branco region were investigated research possible anthropogenic contaminations, heavy metals among their composition, physic-chemical characteristics. These properties can be used define valorisation methods through residue introduction into reinforcement liner application. The results indicated that could help achieve these objectives introduced soil, due enrichment with pozzolanic minerals fine granulometry, while having a low-density, which reduce final weight; however it was considerably different original biomass, contained contaminations concentrations metals.
