History of cement - Understanding Cement

A few years later, in 1845, Isaac Johnson made the first modern Portland Cement by firing a mixture of chalk and clay at much higher temperatures, similar to those used today. At these temperatures (1400C-1500C), clinkering occurs and minerals form which are very reactive and more strongly cementitious.

The major components of Portland cement are tri- and di-calcium silicates, tri-calcium aluminates and tetra-calcium aluminate ferrates [7]. In short, cement is made by heating a mixture of calcareous and argillaceous materials to a temperature of about 1450 °C. In the process, partial fusion occurs and nodules of so-called clinkers are formed.
