Abstract
An investigation into the self-hardening of fly ash from the fluidized bed combustion of wood, peat and forest industry residuals shows the self-hardening strength of eight different ash samples after 28 days of curing at room temperature followed by 7 days at 50 °C to be dependent on its reactive calcium, aluminium and sulphate content. The main reaction products were ettringite and hydrocaluminate. Sulphate was found to be the most typical limiting component for ettringite formation.
