To make cement, a perfect proportion of four basic oxides are important. Calcium oxide should be 65%, iron oxide should be 5%, alumina oxide should be present at 10% and last but not the least silicon oxide should be present at 20% ratio. At around 2000 degree centigrade temperature inside the kiln, a new substance is produced, known as clinker.
