Abstract

This chapter discusses the sources and characteristics (physical, chemical, and mineralogical) of coal ashes, municipal solid waste incineration ashes and modern ashes, criteria for ash utilization in construct industry, current utilizations of ashes, and associated environmental risks. It also discusses the carbonation techniques (direct dry/semidry route, direct aqueous route, and indirect route), the carbonation reaction, and the thermodynamic modeling. For each carbonation method, examples from the literature were discussed. Finally, utilization of the fly ashes to produce Ca-based sorbents as well as the various sintering modification processes was discussed.
