Evaluation of properties of domestic calcareous fly ash and its processing methods

Tomasz Baran , Wojciech Drożdż

Abstract

Characteristics of domestic calcareous fly ash derived from burning of pulverized lignite are presented in the paper. Special attention is given to calcareous fly ashes from Bełchatów Power Station. The variation of chemical composi- tion, average phase composition, as well as both pozzolanic and hydraulic properties of these fly ashes are demonstrated. The results are compared to domestic standards which define the possibilities of using calcareous fly ash as a pozzolanic and hydraulic constituent for cement production. Chosen methods of fly ash processing are also discussed in the paper.
