Based on endothermic peaks attributed to the dehydration of phases formed on hydration, the conditions leading to the formation of so-called ‘delayed’ ettringite were found. This calcium alumino-sulphate hydrate is responsible for lower durability of fluidized bed ash containing material. DTA method is also beneficial in the studies of fluidized bed combustion by-product itself, giving information about the un-burnt carbon content and pozzolanic properties.
