  • 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 ...
