Cement : Manufacture, Chemical Composition, Heat of Hydration

Chemical Composition of Portland 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 compoundsOrdinary Portland Cement - Tests, Properties, .Ordinary/Normal Portland cement is one of the most widely used type of Portland Cement. The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in colour and its quality when it hardens like Portland stone.
