Chemical Composition of CementComposition of cement

Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime silica alumina and iron oxide These oxides interact with one another in the kiln at high temperature to form more complex compounds The relative proportions of these oxide compositions are responsible for influencing the various Composition of cement Introduction Portland cement gets its strength from chemical reactions between the cement and water The process is known as hydrationThis is a complex process that is best understood by first understanding the chemical composition of cement

USA1 Method for treating cement kiln dust Use of Cement Kiln Dust Blast Furnace Slag and Marble

Cement kiln dust can vary in composition from virtually unaltered kiln feed to over 90 alkali sulfates and chlorides depending on process type kiln configuration raw materials fuels process characteristics and points of collection It can vary in particle size from that of fine sand or silt to that of clay with particle size distribution cement kiln dust tailings from mining and quarrying sediments etc Unfortunately very fine solid wastes may often have an unsuitable chemical composition for vitrification and sintering So artificial aggregate can be only obtained by granulation at low temperature of cementitious mixtur
