Abstract

Coal-fly ash consists of fine particles that could containsome heavy metals. The management of coal fly ash remainsa major problem all over the world. An attempt hasbeen made in the present paper to highlight the differenceson chemical composition of Spanish fly ashes whichallows first their classification and second their potentialutilization in several industrial applications. Therefore,Spanish fly ash characterization in terms of chemical analysis,their classification and recommendation of utilizationis assessed. The scope of this paper is limited to fly ashfrom coal fired in thermal power plants. Bottom ash andslag as well as fly ash generated from other industrialsources are beyond the scope of this paper.The major conclusions are related to the utilization of flyash in construction and as adsorbent for the removal ofsome compounds. Fly ash with a lower loss on ignition canbe used in the first field, whereas fly ash with a higher losson ignition can be used in the second one.
