Sequestration of CO2 from atmosphere in the form
of solid carbonates through mineral carbonation is an option
for reduction of CO2 concentration. In the
present study carbon dioxide sequestration has been
performed by using sulfatised hydrated mixture of fly ash
with calcium bearing material in presence of some chemical
activator. Hydrated mixture of both these materials provides
a favorable condition for mineral carbonation. TGA study
indicates that by suitable conditioning 1ton of carbonated
ash absorbs 100kg of CO2 in atmospheric
