Reuse of Ash and Solid Residues from Thermoconversion Processes in the Building Materials Industry

Ash resulting from thermoconversion processes of solid fuels (biomass), and other residues encountered in this book (e.g., spent sorbent from calcium looping processes; mixtures of ash and spent sorbent from fluidised bed combustion processes with in situ desulphurisation), can find fields of reuse such as supplementary cementitious materials, pozzolanic additions, raw materials to replace natural ones, depending on the properties of the residues and the type of cement (for example, Portland, sulphoaluminate) to which one refers.
