    How Cement Is Made

    The finely ground raw material or the slurry is fed into the higher end. At the lower end is a roaring blast of flame, produced by precisely controlled burning of powdered coal, oil, alternative fuels, or gas under forced draft. As the material moves through the kiln, certain elements are driven off in the form of gases.

This property and the related property of not undergoing chemical change by water in later life are most important and have contributed to the widespread use of concrete as a building material.
