Original MSWI fly ash samples were subjected to particle size distribution analysis which was performed by a laser particle size analyser (Microtrac, S3500). In order to improve the homogeneity among particles, the samples were ground for 4 h by a ball grinding mill and sieved through a 200-mesh (75 µm).

Class-F fly ash (FA) from a coal-fired thermal power station was subjected to high energy ball milling-induced mechanochemical activation aided by a surfactant. Subsequently, ethylene-octene copolymer/mechanochemically activated FA (EOC/MCA-FA) composites were prepared by solution casting. The surface modification of FA was confirmed from contact angle measurements and FTIR

Exploring the many uses of fly ash - EE Publishers

Fly ash is not a hydraulic material and, strictly speaking, it does not hydrate to form cementitious hydrates. It is a pozzolan, which is defined as a siliceous or a siliceous material which, though itself possessing little or no cementitious value, will, in a finely divided form and in the presence of moisture, react chemically with calcium hydroxide (Ca(OH) 2) at ambient temperature to form
