Properties and application of zeolitized fly ash

Abstract

The combustion of coal produces large quantities of fly ash. This waste product is at present used for the production of building materials. This use may be reduced for a number of reasons, such as: stricter environmental regulations, changes in combustion techniques and competition with other residual materials. To avoid a future surplus, there is a growing interest in new applications of coal fly ash (CFA). This thesis is the result of a research project carried out to investigate the possibility ofusing CFA for the synthesis of zeolites.
