Cement : Physical Properties and Types of Cement

Formation of cracks in large body of concrete due to heat of hydration has focussed the attention of the concrete which produces less heat, at a low rate during the hydration process. A low-heat evolution is achieved by reducing the contents of C 3 S and C 3 A which are the compounds evolving the maximum heat of hydration and increasing C 2 S.

Preparation. Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln.This is accomplished by heating the material to above 825 °C (1,517 °F), a process called calcination or lime-burning, to liberate a molecule of carbon dioxide (CO 2), leaving quicklime.
