Coal bottom ash as light fill material in construction

In todayʹs society, there are increasing requirements on recirculating wastes and residues to the greatest possible extent. Among the waste products with major potentials for recycling are ash and slag from energy production. The combination of interesting material properties and environmental acceptability makes these products suitable for application as construction materials. Although Swedish utilisation of residues from coal combustion has until recently been limited, a small number of projects have been carried out. The predominant application for ash so far has been as light fill material.
