1THE CONTENTS OF FLY ASH AND ITS USESAbstractThe result of combustion of coal is termed as fly ash or pulverized fuel ash. It is made up ofminute particles and is driven out of the boilers of the thermal power plant. It is collected byproper filtering methods. The main contents fly ash is aluminum and siliceous material that iscapable of forming cement in presence of water. The report elaborates the contents and uses offly ash as an additional cement type material for production of Portland concrete cement. Fly ashcan be considered as a partial replacement of Portland cement, which is mainly used inproducing concrete. The literature review and the detailed analysis of component and use of flyash are elaborated in this report.

3THE CONTENTS OF FLY ASH AND ITS USES1.0 IntroductionBy product of burning pulverized coal in power plant that generates electric, is known asfly ash. This product can be used as an additional and supplementary form of Portland cement.Fly ash is formed by the fusion of the impurities present in coal, which includes clay, feldspar,quartz and shale. The mineral impurities that are present in the coal fuse in suspension due to theexcessive heat generated as a result of Combustion. However, on rising up, these fused materialscools down and solidifies to become a spherical glassy particle, which is known as fly ash.Electrostatic precipitators is used in collection and filtration of the fly ash that is collected fromthe exhaust gases (Anastasiou, Filikas and Stefanidou, 2014). Fly ash can be used instead of ofPortland cement as it reacts with the byproduct of the reaction between water and cement,helping in improving the desirable features of concrete. However, the chemical reaction thattakes place between fly ask and calcium hydroxide is much slower as compared to the cementand water. Therefore, the process of hardening of the concrete is also delayed. Moreover, thevariable properties of fly ash can create certain challenges for producer and finisher in differentprojects. The detailed literature review and the different uses of fly ashes are elaborated in thefollowing paragraphs-2.0 Literature ReviewAccording to Thomas (2013), fly ash can be considered as a supplementary cementmaterial for the development of Portland cement concrete. It contributes to the features ofhardened concrete through hydraulic activity. It is basically a siliceous and aluminous materialthat has cement like value and is capable of reacting chemically with calcium hydroxide in
