Other Components
Cement is made from materials mined from the earth and processed using energy
provided by fuels. Additional materials, such as fly ash, kiln dust and slag may also be
introduced into the cement manufacturing process. A chemical analysis of cement may
reveal trace amounts of naturally occurring but potentially harmful chemical compounds
such as free crystalline silica, organic compounds, potassium and sodium components,
