The most common raw material in common cement production are:

  1. Limestone (supplies the bulk of the lime)
  2. Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide)
  3. Other supplementary materials such as sand, fly ash/pulverised fuel ash (PFA), or ironstone to achieve the desired bulk composition
