Portland cement clinker was first made (in 1825) in a modified form of the traditional static lime kiln. The basic, eggcup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker. For nearly half a century, this design, and minor ...

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.
